Question

CH3 is less stable than? a) CH3-CH2 b) CH3-CH-CH3 c)CH2-NO2 d) CHCH-C2H5

Answer 1

Answer: Option (c) CH2-NO2

Explanation:

Answer 2

Answer:

c) CH2-NO2

Explanation:

Because, presence of -NO2 group increases stability and acidic character since acidity is directly proportional to stability , NO2 is highly electron withdrawing group and so increases stability.

Also, stability is inversely related with  basicity.
