Question

During the formation of amides from amino acids-

• A. $COOH$ part of acid is replaced by $N{H}_2$
• B. $N{H}_2$ part of acid is replaced by $COOH$
• C. $OH$ part of acid group is replaced by $N{H}_2$
• D. $N{H}_2$ part of acid is replaced by $OH$

Answer 1

The correct option is C $OH$ part of acid group is replaced by $N{H}_2$

The addition of ammonia to a carboxylic acid form an amide. Amides are derivatives of amino acids in which the hydroxyl group $\left(OH\right)$ is replaced by the amino group $\left(N{H}_2\right)$.
So, the correct answer is option 'c'.
