Question

Write the name of the product formed by the action of LiAlH4/ether on acetamide.

Short Note

Solution

Ethylamine OR Ethanamine

Explanation:

Primary amines having the same number of carbon atoms can be obtained by the reduction of amides by LiAlH4 in ether or by Na/C2H5OH.

\[\begin{array}{cc}
\ce{O}\phantom{..................................................}\\
||\phantom{..................................................}\\
\ce{\underset{(Acetamide)}{CH3 - C - NH2} + 4[H] ->[LiAlH4, ether H3O^⊕][or Na/C2H5OH] \underset{(Ethylamine)}{CH3 - CH2 - NH2} + H2O}
\end{array}\]
