The stability of carbanions in the following. (i) RC = C ⊖ (iii) R 2 C = C ⊖ H (iv) R 3 C ⊕ = C ⊖ H 2 is in the order of

Options

  1. A(iv) > (ii) > (iii) > (i)
  2. B(i) > (iii) > (ii) > (iv)
  3. C(i) > (ii) > (iii) > (iv)
  4. D(ii) > (iii) > (iv) > (i)

Correct answer

C. (i) > (ii) > (iii) > (iv)

Step-by-step solution

Higher the no. of electron releasing group lower will be stability of carbanion, and vice versa. So the order of stability of carbanions is
