The angle strain in cyclobutane is

Options

  1. A24^ 44^
  2. B29^ 16^
  3. C19^ 22^
  4. D9^ 44^

Correct answer

D. 9^ 44^

Step-by-step solution

The s p³ hybridised carbon atom have bond angle of 109^ 28^ (tetrahedral angle). But in cyclobutane the bond angle is 90^ due to square shape. Therefore, angle strain = 1 2 (109^ 28^ -90^ )=9^ 44^
