NEET levelSingle correct optionDifficulty 1 of 3o1063

Acetone reacts with hydroxylamine, $NH X_{2} OH$ , in weakly acidic medium. The product is

A $CH X_{3} - CO - NH - OH$
B $(CH X_{3}) X_{2} CH - NH X_{2}$
C $(CH X_{3}) X_{2} C (OH) - NHOH, isolated as a stable compound$
D $(CH X_{3}) X_{2} C = N - OH$

Answer: D

The nitrogen of

NH X_{2} OH

adds to the carbonyl carbon and the carbinolamine loses water, giving the oxime

(CH X_{3}) X_{2} C = N - OH

. The carbinolamine is not isolated.
