NEET levelSingle correct optionDifficulty 1 of 3co034

Ethanal reacts with hydroxylamine, $NH X_{2} OH$ , in weakly acidic medium to give

A $CH X_{3} CH X_{2} NHOH$
B $CH X_{3} CH = NOH$
C $CH X_{3} CONHOH$
D $CH X_{3} CH X_{2} ONH X_{2}$

Answer: B

Carbonyl compounds condense with

NH X_{2} OH

with loss of water to give oximes,

C = N - OH

. Ethanal gives ethanal oxime,

CH X_{3} CH = NOH

.
