Q. Statement (A) Carboxylic acid can be obtained by the reaction of $R-C \equiv N$ with $H _{3} \stackrel{\oplus}{ O }$ under mild reaction conditions.
Statement (B) Hydrolysis of $R-C \equiv N$ in alkaline aqueous medium gives $R-CO \overset{⊖}{O}\overset{\oplus}{N}a$ and $\overset{¨}{N}H _{3}$ as products.
The correct answer is

TS EAMCET 2019

Solution:

Carboxylic acid can be obtained by complete hydrolysis of $R-CN$. Therefore, statement $(A)$ is incorrect.
