Alcohols Phenols And Ethers Question 70
Question: Which one of the following substituents at para- position is most effective in stabilizing the Product of the reaction is:
Options:
A) $ -CH_3 $
B) $ -OCH_3 $
C) $ -COCH_3 $
D) $ -CH_2OH $
Show Answer
Answer:
Correct Answer: C
Solution:
[c] Electron withdrawing group stabilises the benzene ring due to delocalisation of charge. $ -CH_3 $ and $ -CH_2OH $ are electron donating group and hence decrease the stability of benzene ring $ -OCH_3 $ is weaker electron withdrawing group than- $ -COCH_3 $ . Hence $ -COCH_3 $ group more stabilize the phenoxide ion at p-position.
