Which of the following is NOT optically active compound?

Which of the following is NOT optically active compound?
  1. 1,2-Diiodobutane
  2. 1,3-Diiodobutane
  3. 1,4-Diiodobutane
  4. 2,3-Diiodobutane

Solution

1,4-Diidobutane has plane of symmetry. Thus, it does not rotate the plane of plane polarized light and is optically inactive. $\mathrm{I}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{I}$
