A pair of compounds having the same boiling points are

Options

  1. Acis but-2-ene and trans but-2-ene
  2. Bn -hexane and neo-hexane
  3. Cbenzene and naphthalene
  4. D(+) butan-2-ol and (-) butan-2-ol

Correct answer

D. (+) butan-2-ol and (-) butan-2-ol

Step-by-step solution

d -and l -isomers (enantiomers) have identical chemical and physical properties. They are indistinguishable from each other except for the direction of rotation of the plane polarised light. Thus ( + ) butan-2-ol and (-) butan-2-ol will have same boiling points.
