Which of the following compounds will exhibit cis-trans (geometrical) isomerism?

Options

  1. A2-butene
  2. BButanol
  3. C2-butyne
  4. D2-butenol

Correct answer

A. 2-butene

Step-by-step solution

Key Idea Compounds which have at least one double bond ( C = C ) and the groups attached with double bonded carbon atoms are different, exhibit geometrical isomerism. CH ₃ CH ₂ CH ₂ CH ₂ OH no geometrical isomers butanol CH ₃ C CCH ₃ no geometrical isomers CH ₃ CH ₂ C ( OH )= CH ₂ no geometrical isomers.
