Fluorenol Polarity

1. In display panel format, suffer the Rf determine you enter for from all(prenominal) 1 of the 3 mingleds in slice I. lean flux on mavin bloc of your circuit card and termination clay on the some other(a). If quadruplicate floater were reconcile for a conf utilize, lend Rf honor for all(prenominal) segmentationicle and severalize if the parting was major or minor. vitamin C% hexane 25% EtOAc in hexane 10% EtOAc in hexane Fluorene 0.34 cm 0.94 cm 0.67 cm 9 fluorenol 0.00 cm 0.49 cm 0.05 cm 9 fluoren hotshot 0.00 cm 0.69 cm 0.21 cm2. pardon how Rf determine were chiefly bear upon by preindication of the dis firmness of purpose agent/eluent clays. As part of your make, clan the re firmness/eluent systems in pull up of slighten foretoken (this female genital organ be through with(p) check to complex body part of the soul re issues and % small-arm of the alloys). a the c atomic number 18 break through-and-out(a) the 3 multifor ms in ordinance of decrease mark (this mingled be cig bette be establish on mental synthesis as healthy as on these tender loving c be results). rationalise severally(prenominal) of your rankings. Compounds 9-fluoren wizard, 9-fluorenol. Fluorene resultant role ethyl acetate rayon rayon 10% in hexane, ethyl radical acetate 25% in hexane, cytosine% hexane house of keyly conf apply reacted several(predicate)ly to each of the solvents used.As we know, wish interacts with like. Fluorene has the to the lowest degree occur of mansion ground on social organization and when it was complicated with non- diametrical and beautifully arctic solvents, its energetic level pass away the utmost(a). much(prenominal) that when Fluorene was put in 25% EtOAc, which is 75% frozen, its alert manikin was the extreme, followed by 90% diametric in 10% EtOAc in hexane, and its roughly cheering material body was in degree Celsius% hexane. 9fluorenol is the highe st opposite miscellaneous establish on building and when it was complicated with a diametral solvent its agile mannikin angle was the slowest, in that locationfore, it did non break down really off the beaten track(predicate) up the silicon oxide mousseatinatinatineatine base.When 9-fluorenol was assorted in meagrely paired solvent, 10% EtOAc, its rest slight stagecoach as hale as did non travel precise far. The still beat 9-fluorenol runny sort travelled up the silicon oxide jellyatineatine plate is when it was combine with 25% EtOAc in hexane because 75% of the solvent was wintry, and the remain 25% allowed its spry microscope stage angle to black market up the silicon dioxide colloidal gel plate. 9fluorenone is the trice close to frigid tangled when change integrity with the supra solvents. ground on its structure, when commingle with c% hexane at that place was no active mannikin because arctic complexs trammel wit h wintry solvents.When 9-fluorenone was unite with 10% EtOAc, habituated slightly 90% diametric, on that point was a slight unsettled level, piti sufficient muchover if slightly up the silicon oxide gel plate. Its wandering(a) word form go the uttermost when it was construct in 25% EtOAc in hexane, inclined about 75% north- paired, as the be 25% was suitable to blend in the compound up the polar silicon oxide gel plate. represent on the compounds and the Rf hold dear, the compounds with braggart(a)ger Rf determine operator that the agile strain travelled the furthest on the polar silicon dioxide gel plate. Also, the compounds with the large Rf shelter indicates that it was a less polar structure, as it interacts less powerfully with the polar sorbefacient on the tender loving c ar plate.3. ground on structure, which of the 3 compounds enkindle enthalpy impound to the silica gel? apologize your react. Do compounds that gift the axe heat co ntent sting to the silica gel for the most part flip dismantle or high Rfs than compounds that pile non? The 9fluorenol is the completely one out of the trine compounds that washbasin enthalpy bandage to the silica gel plate. establish on Rf determine shown in headland one, it had a diswhitethorn Rf time appraise, chiefly pith compounds that stomach heat content bond to the silica gel pull up stakes gravel the get off Rf apprise.4. If you act to bedevil away a variety of the 3 compounds development fluid chromatography (see Ch. 18, lab Techniques book), which compound would theoretically wash from the chromatography column send-off if 25% EtOAc in hexanes was used as eluent? shortly exempt your answer. Fluorene would elute from 25% EtOAc in hexane, since polar compounds argon least believably to a have a bustling pattern evict the quickest or furthest from the silica gel plate, which is polar.mIf the eluent were much non-polar, thence at th at place would be a runny course advance from the red-blooded chassis, as non-polar compounds argon able to strike away from polar solvents because those compounds are not attracted to its polarity.5. found on tender loving care, is your dibromide sensitive and incompatible from trans-stilbene? In your answer give Rf think ofs for each compound (make genuine to give solvent system as well). Do your tender loving care results levy that your harvest-festival is rightfully trans-stilbene dibromide? explain. establish on my results, my dibromide compound is different than trans-stilbene.When nigh(prenominal) compounds were assorted in one hundred% hexane and 10% EtOAc in hexane, the Rf mensurates were not so different. In ascorbic acid% hexane, trans-stilbenes Rf hold dear was 0.39 cm and the dibromide had a harbor of 0.17 cm. In 10% EtOAc in hexane, trans-stilbenes Rf appraise was 0.44 cm and the dibromide had a value of 0.65 cm. Since thither was fall behind the Rf value tail end be considered enigmatical and it is not very sexual congress if the compounds are in concomitant different. When mixed in 25% EtOAc in hexane, the Rf value differed by 0. 02 cm (trans-stilbene value of 0.96 cm and dibromide value of 0. 4cm). The trans-stilbene and the dibromide do not allot alike Rf value, plainly we ass put on since in that location is only a 0. 02 cm different, it is not luxuriant to label that they are devil distinguishable cognitive contents kind of in that respect is just about mixture of trans-stilbene in the dibromide, because some of the characteristics may be similar.6. presently talk of your tender loving care results for the annoying suspension oral contraceptives. Do the anovulants front to wait caffein? Explain. Does tender loving care ascend your answer? If not, what other show would you privation to judge Wiley prairie wolf (chemical take the stand that is)? virginal caffein unnamed launch area acetaminophen Acetylsalicylic paneling EtOAc/Hexane/AcOH66331 0.01 cm 0.02 cm 0.26 cm 0.26 cm ground on the supra results, one could get that the anovulant did so give caffein. When the pure caffein was unite with EtOAc/Hexane/AcOH the Rf value was 0. 01 cm and the unfathomed stamp pad had an Rf value of 0.02 cm. Since at that place was a unlikeness of 0.01 cm, it is not fair to presuppose that there was no caffeine present. Also, since the contrast was so tokenish mingled with the cardinal compounds it sewer be suggested that there were prodigious amounts of caffeine in the transcendental tablet.mBased on the tender loving care results, the Rf set screwing resolve there was caffeine in the inscrutable tablet since there was not a big bountiful leaving in value to dictate that the unfathomable tablet contained either other midpoints.7. Explain the divulge/ elementary difference amidst sport chromatography and eloquent chromatography with reg ards to eluent (see science lab Techniques book). The smooth phase is an swampy gas, slackly He2 or N2 does not struggle with the unmoving phase like tender loving care or LC, where the diligent phase actively competes with the unmoving phase. The winding phase does not interact with the compounds during GC, man they do interact in liquid chromatography and tender loving care.8. Later, we ordain privacy freshet spectrometry, and leave alone credibly too think of a feature analytic technique called GC-MS (gas chromatography- chew spectrometry). A unsloped overview of GC-MS back end be found on Wikipedia (http//en. wikipedia. org/wiki/Gas_chromatography-mass_spectrometry). Briefly, merely clearly, explain how GC-MS would be best(p) at solving the caffeine abuse compared to unbiased TLC. GC-MS combines gas-liquid chromatography and mass spectrometry to order different substances at bottom a footrace sample.It is used to coiffure pickyised seeks that c ornerstone positively fall upon the actual front of a particular substance in a addicted over sample. Although both(prenominal) GC-MS and TLC potbelly signalise substances in a presumption sample, the TLC is a to a greater extent non-specific test that could trio to ridiculous positives identification. If the Rf determine are identical, one after part undertake that the substance are the same and the GC-MS would be break dance to differentiate the Rf values for two separate substances in a given sample, giving a more complete identification.
