Arrange the following in increasing order of acidic charater.

Options

  1. AI < II < III < IV
  2. BI < IV < II < III
  3. CIV < III < II < I
  4. DII < III < IV < I

Correct answer

B. I < IV < II < III

Step-by-step solution

Acidic character stability of conjugate base. tability of anion -M -I 1 +I 1 Hyperconjugation Mesomeric effect is more than hyperconjugation and -M effect of - NO ₂ will not operate at m -position. Correct order is III > II > IV > I.
