Goc Theory Part 7 Ques1

Question: Which of the following species is most stable due to resonance?

Options:

A) $ CH_3-CH=CH-CH_3 $

B) $ CH_3-CH=CH-CHO $

C) $ CH_3-CH=CH-COOH $

D) $ CH_3-CH=CH-NO_2 $

Show Answer

Answer: d

Explanation:

A) $ CH_3-CH=CH-CH_3 $ has limited resonance structures.

B) $ CH_3-CH=CH-CHO $ has some resonance stabilization.

C) $ CH_3-CH=CH-COOH $ has resonance stabilization but less than option d.

D) $ CH_3-CH=CH-NO_2 $ has the most extensive resonance stabilization due to the strong electron-withdrawing nature of the $ NO_2 $ group.
