Q. The formula of acetaldehyde semicarbazone:
Jharkhand CECE
Jharkhand CECE 2002
A
$ CH_{3}-CH=NNHCONHCH_{3} $
B
$ CH_{3}-CH=N-OH $
C
$ CH_{3}CH=N-NHCONH_{2} $
D
$ CH_{3}-CH=N-NHCONH-CONH_{2} $
Solution:
Write reaction to find correct answer
$\underset{\text{acetaldehyde}}{CH_3 - \overset{\underset{||}{O}}{C} - H} + \underset{\text{semicarbazide}}{H_2NNHCONH_2} \rightarrow \underset{\text{acetaldehyde semicarbazone}}{CH_3 - \overset{\underset{|}{H}}{C} = NNHCONH_2}$
