p The advantage of using the Eschweiler-Clarke method for preparing N ,N-dimethylbenzalmine preferably than the reductive alkyl radical groupation method because the loss of the piss pinch is thermodynamic any toldy disfavored by the presence of a large-mouthed amount of water in itrs environment . This therefore , suggestes that in some cases the chemical reaction proceeds via reduction of the hydroxyl aminoalkane species2 . Below are reference spectra of benzyl radical radical aminoalkane , N-methylbenzyl amine , and N ,N-dimethylbenzylamine . These spectra were acquired at SDBSWeb http /www .aist .go .jp /RIODB /SDBS (access date - 3 /28 /06 . Indicate on these spectra the signals in the functional group touch that are most indicative of the extent of substitution onnitrogen (primary amine vs . secondary amine , vs ter tiary amine . How could you use IR to determine if an unknown amine was a primary amine or a secondary amineAnswer1 ? amine : two bands from 3400-3300 and 3330-3250 cm-12 ? amine : one band from 3350-3310 cm-13 .

Explain why we expect all of the initially formed N-methyl benzyl amine to be converted to N ,N-dimethyl benzyl amine product under the conditions of the Eschweiler-Clarke response (Hint : consider the relative amounts of reagents used in this experimentAnswerThe formed N-methyl benzyl amine in the reaction 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-dimeth yl benzyl amineTHE ALDOL CONDENSATION1 . Wri! te the aldol product that would be obtained if dibenzyl ketone condensed with itself (Only a single condensation . This product is not appalling because benzil is more reactive toward nucleophilic attack 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: OrderEssay.net
