Statement (A) Carboxylic acid can be obtained by the reaction of `R-C-=N` with `H_(3)overset(o+)"O"` under mild reaction conditions.
Statement (B) Hydrolysis of `R-C-=N` in alkaline aqueous medium gives `R-"CO"overset(Θ )"O"overset(o+)Na` and `overset(●●)"N""H"_(3)` as products.

Options

A. Both (A) and (B) are correct
B. Both (A) and (B) are not correct
C. (A) is correct, but (B) is not correct
D. (A) is not correct but (B) is correct

Answer

D

Explanation

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

When alkyl cyanide hydrolysed in presence of alkaline medium, `R-CO overset(-)Ooverset(+)Na-Na` and ammonia gas are obtained
`R-C-=N underset(NaOH)overset(H_(2)O //H^(+))rarr R-underset("O")underset("||")C-overset(-)Ooverset(+)Na+NH_(3)`
Therefore, statement (B) is correct.
