Consider the following carbocations, stability of carbocations increasing order I C 6 H 5 C + H 2 II C 6 H 5 CH 2 C + H 2 III C 6 H 5 C + HCH 3 IV C 6 H 5 C + CH 3 2

Options

  1. A(II) <(I) <(III) <(IV)
  2. B(I) <(II) <(III) <(IV)
  3. C(III) <(II) <(I) <(IV)
  4. D(IV) <(I) <(III)< (I)

Correct answer

A. (II) <(I) <(III) <(IV)

Step-by-step solution

Resonance and inductive effect decide stability of carbocations. ∴ Correct order of stability is (II) <(I) <(III) <(IV)
