Question

Action of hydrazine on aldehydes and ketones gives compound of the general structure

• A.
  $>C=N-N{H}_2$
• B.
  $>C=N-OH$
• C.
  $>C=N-NH-CON{H}_2$
• D.
  $>C=N-NH-C_6{H}_5$

Answer 1

The correct option is A

$>C=N-N{H}_2$
Action of hydrazine on aldehydes and ketones gives compound of the general structure: $>C=N-N{H}_2$

b) Aldehydes reacts with hydroxyl amine to form oxime.
$Ph-CH=CH-CH\left(C{H}_3\right)-CHO+N{H}_{2}OH\rightleftharpoons Ph-CH=CH-CH\left(C{H}_3\right)-CH=NOH+H_{2}O.$
c)
d)
