p The advantage of employ the Eschweiler-Clarke method for preparing N ,N-dimethylbenzalmine sooner than the reductive alkyl group throngation method because the loss of the piss mite is thermodynamic exclusively toldy disfavored by the presence of a adult amount of water in itrs environment . This therefore , suggestes that in some cases the response continue via reduction of the hydroxyl aminoalkane species2 . Below are cite spectra of benzyl group radical aminoalkane , N-methylbenzyl amine , and N ,N-dimethylbenzylamine . These spectra were acquired at SDBSWeb http / entanglement .aist .go .jp /RIODB /SDBS (access date - 3 /28 /06 . Indicate on these spectra the signals in the functional group contend that are most indicative mood of the extent of substitution onnitrogen (primary amine vs . alternate amine , vs ordinal amine . How could you use IR to determine if an unknown amine was a primary amine or a secondary amineAnswer1 ? amine : cardinal bands from 3400-3300 and 3330-3250 cm-12 ? amine : one band from 3350-3310 cm-13 .

justify why we expect all of the initially formed N-methyl benzyl amine to be reborn to N ,N-dimethyl benzyl amine product under the conditions of the Eschweiler-Clarke response (Hint : consider the relative amounts of reagents use in this experimentAnswerThe formed N-methyl benzyl amine in the reaction is thermodynamically unstable callable 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 . carry through the aldol product that would be obtained if dibenzyl ketone condensed with itself (Only a single ejection seat . This product is not grandiloquent because benzil is more reactive toward nucleophilic contend 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 acquiring in the way , instead of just...If you want to get a full essay, order it on our website: Orderessay
