Which of the following compounds gives a tertiary amine on reduction ? .

Options

A. Nitriles
B. Amides
C. Oximes
D. Nitroalkanes

Answer

B

Explanation

Reduction of a nitrile an oxime or a nitroalkane yields a primary amine whereas eeducation of an amide can yield a primary secondary or tertiary amine Reduction of N,N-disubstituted primary amide converts the carbony1 group `(C=O)` into methylene group `(CH_(2))` to yield a tertiary amine
`CH_(3)CH_(2)-overset(O)overset(||)C-underset(CH_(3))underset(|)N-CH_(3)underset(2H_(2)O)overset(1LiAIH_(4) ether)rarrCH_(3)CH_(2)CH_(2)- underset(3^(@) amine)underset(CH_(3))underset(|)N-CH_(3)` .
