p The advantage of victimization the Eschweiler-Clarke regularity for preparing N ,N-dimethylbenzalmine quite than the reductive alkyl radicalation method because the loss of the piss tittle is thermodynamic solely toldy disfavored by the presence of a big(p) amount of water in itrs environment . This therefore , suggestes that in some cases the answer regaining via reduction of the hydroxyl aminoalkane species2 . Below are point of reference spectra of benzyl radical radical aminoalkane , N-methylbenzylaminoalkane , and N ,N-dimethylbenzylaminoalkane . These spectra were acquired at SDBSWeb http /ne 2rk .aist .go .jp /RIODB /SDBS (access date - 3 /28 /06 . Indicate on these spectra the signals in the functional group allot that are most common mood of the extent of substitution onnitrogen (primary amine vs . unoriginal amine , vs third 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 .

beg off 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 employ in this experimentAnswerThe formed N-methyl benzyl amine in the reaction is thermodynamically unstable due to the presence of electron withdrawing phenyl group Hence , a nonher alkyl group easily substituted on the nitrogen to form N ,N-dimethyl benzyl amineTHE ALDOL CONDENSATION1 . save up the aldol product that would be obtained if dibenzyl ketone condensed with itself (Only a single compressing . This product is not august because benzil is more reactive toward nucleophilic firing than dibenzyl ketoneAnswer : Aldol condensation is a reaction of aldehydes , ketones do not condenses itself on the first carbonyl groupAnswer : Steric hindrance . You have two R groups flopping around and acquiring in the way , kind of of just...If you want to get a full essay, order it on our website: Ordercustompaper.com
