Aldehydes Ketones Question 52
Question: Among the following the order of reactivity towards nucleophilic addition is
Options:
A) $ CH_3CHO>CH_3COCH_3>HCHO $
B) $ HCHO>CH_3CHO>CH_3COCH_3 $
C) $ CH_3CHO>HCHO>CH_3COCH_3 $
D) $ CH_3COCH_3>CH_3CHO>HCHO $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Presence of alkyl group in carbonyl compounds decreases their reactivity towards nucleophilic addition. Further greater the number of such groups lesser will be the reactivity towards nucleophilic addition
$ \therefore $ correct order is $ HCHO>CH_3CHO>CH_3COCH_3 $
