Strength of acidity is in order:

  • A
    II>I
  • B
    I>II
  • C
    I=II
  • D
    Cannot be determined
✓

Answer

  1. I>II

Explanation:

As we know that the strength of acidity inversely depends upon the +I effect.

Thus, due to +I effect of methyl group (−CH3​), I is more acidic than II.

Hence the correct order of strength of acidity is-I>II.
