Question

write the reaction and condition for the conversion
acetic acid to ethylamine

Answer 1

$$\begin{gathered} \text{Acetic acid is converted to acetyl chloride} \\ {\mathrm{CH}}_3\mathrm{COOH}\stackrel{{\mathrm{SOCl}}_2}{\to }{\mathrm{CH}}_3\mathrm{COCl}+{\mathrm{SO}}_2+\mathrm{HCl} \\ \mathrm{Acetyl}\mathrm{chloride}\mathrm{in}\mathrm{presence}\mathrm{of}\mathrm{ammonia}\mathrm{gives}\mathrm{acetamide}\mathrm{which}\mathrm{on}\mathrm{reaction}\mathrm{with}\mathrm{lithium}\mathrm{aluminium}\mathrm{hydride}\mathrm{gives}\mathrm{Ethylamine}. \\ {\mathrm{CH}}_3\mathrm{COCl}\underset{-{\mathrm{NH}}_4\mathrm{Cl}}{\overset{{\mathrm{NH}}_3\left(\mathrm{excess}\right)}{\to }}{\mathrm{CH}}_3{\mathrm{CONH}}_2\stackrel{{\mathrm{LiAlH}}_4/\mathrm{ether}}{\to }{\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{NH}}_2 \\ \mathrm{Regards} \end{gathered}$$
