Question

Aldehyde with NH2.NH2 forms (A) hydrazones (B) aniline (C) nitrobenzene (D) None of these

Tardigrade Admin · Accepted Answer

Aldehydes and ketones with N H2 . N H2 forms hydrazones. RCHO + H 2 N . NH 2 arrow underset text ald. hydrazone RCH = N . NH 2+ H 2 O R2 CO + H 2 N ⋅ NH 2 arrow R 2 C = N . NH 2+ H 2 O

Q. Aldehyde with $N H_{2} . N H_{2}$ forms

hydrazones

aniline

nitrobenzene

None of these

Aldehydes and ketones with $N H_{2} . N H_{2}$ forms hydrazones.
$RC H O + H_{2} N . N H_{2} \to ald. hydrazone RC H = N . N H_{2} + H_{2} O$
$R_{2} CO + H_{2} N \cdot N H_{2} \to R_{2} C = N . N H_{2} + H_{2} O$
