Decreasing order of stability of following alkenes is (i) C H 3 - C H = C H 2 (ii) C H 3 - C H = C H - C H 3 (iii) CH 3 − C = CH − CH 3 | CH 3 (iv) CH 3 CH 3 | | CH 3 − C = C − CH 3

Options

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

Correct answer

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

Step-by-step solution

Stability ∝ No. of hyper conjugating structures ∝ No. of α -hydrogens.
