Wired Faculty App

Out of the following, the alkene that exhibits optical isomerism is

  • 2–methyl–2–pentene

  • 3–methyl–2–pentene

  • 4–methyl–1–pentene

  • 3–methyl–1–pentene

Solution

D.

3–methyl–1–pentene

3-methyl-1-pentene is optically active due to presence of chiral carbon, indicated by red star
