p The advantage of using the Eschweiler-Clarke regularity for preparing N ,N-dimethylbenzalmine sort of than the reductive alkyl group pigeonholingation method because the loss of the piss pinch is thermodynamic only toldy disfavored by the presence of a macroscopic amount of water in itrs environment . This therefore , suggestes that in some cases the receipt military issue via reduction of the hydroxyl aminoalkane species2 . Below are file name extension spectra of benzyl radical radical aminoalkane , N-methylbenzyl aminoalkane , and N ,N-dimethylbenzylaminoalkane . These spectra were acquired at SDBSWeb http / web .aist .go .jp /RIODB /SDBS (access date - 3 /28 /06 . Indicate on these spectra the signals in the functional group part that are most apocalyptical of the extent of substitution onnitrogen (primary aminoalkane vs . indirect amine , vs tertiary amine . How could you use IR to determine if an unknown amine was a primary amine or a secondary amineAnswer1 ? amine : devil bands from 3400-3300 and 3330-3250 cm-12 ? amine : one band from 3350-3310 cm-13 .

rationalise why we expect all of the initially formed N-methyl benzyl amine to be regenerate to N ,N-dimethyl benzyl amine product under the conditions of the Eschweiler-Clarke response (Hint : consider the relative amounts of reagents employ in this experimentAnswerThe formed N-methyl benzyl amine in the reception is thermodynamically unstable callable to the presence of electron withdrawing phenyl group Hence , another alkyl group easily substituted on the nitrogen to form N ,N-dimethyl benzyl amineTHE ALDOL CONDENSATION1 . economize the aldol product that would be obtained if dibenzyl ketone condensed with itself (Only a single abridgment . This product is not awful because benzil is more reactive toward nucleophilic round down than dibenzyl ketoneAnswer : Aldol condensation is a reaction of aldehydes , ketones do not condenses itself on the first carbonylic groupAnswer : Steric hindrance . You have two R groups flopping around and getting in the way , instead of just...If you want to get a full essay, order it on our website: Ordercustompaper.com
