Correct answer: D. (A) is not correct but (B) is correct

Carboxylic acid can be obtained by complete hydrolysis of

R-\mathrm{CN}

. Therefore, statement

(A)

is incorrect. Statement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.

When alkyl cyanide hydrolysed in presence of alkaline medium,

R-\mathrm{COOO}^{-}+\mathrm{a}-\mathrm{Na}

and ammonia gas are obtained Statement (A) Carboxylic acid can be obtained by the reaction of R-C N with H_3 O under mild reaction conditions.

Therefore, statement (4) is correct.
