In the following structure, the double bonds are marked as I ,   II , III and IV . Geometrical isomerism is not possible at the site(s):

Options

  1. AI and III
  2. BIII
  3. CI
  4. DIII and IV

Correct answer

C. I

Step-by-step solution

The different group should be attached to each sp 2 hybridised C - atom. It has 2   CH 3 group at I - C , so it will not show geometrical isomerism.
