Q. Which of the following reactions is not an example for nucleophilic addition - elimination reaction?
NEET
NEET 2022
Aldehydes Ketones and Carboxylic Acids
A
$CH _3 CHO + NaHSO _3$
59%
B
$CH _3 CHO + NH _2 OH\rightleftharpoons CH _3 CH = N - OH + H _2 O$
10%
C
$CH _3 CHO + C _6 H _5 NHNH _2 \rightleftharpoons$ $CH _3 CH = N - NHC _6 H _5+ H _2 O$
16%
D
$CH _3 CHO + NH _3 \rightleftharpoons CH _3 CH = NH + H _2 O$
15%
Solution:
$CH _3 CHO + NaHSO _3 \rightleftharpoons CH _3- \underset{\overset{|}{H}}{\overset{\underset{|}{O}H}{C}} - OSO _2 Na$
Nucleophilic addition reaction.
