A flask contains a mixture of isohexane and 3 -methylpentane. One of the liquids boils at 63 o C while the other boils at 60 o C . What is the best way to separate the two liquids and which one will be distilled out first?

Options

  1. Afractional distillation, isohexane
  2. Bsimple distillation, 3 -methylpentane
  3. Csimple distillation, isohexane
  4. Dfractional distillation, 3 -methylpentane

Correct answer

A. fractional distillation, isohexane

Step-by-step solution

Liquid having lower boiling point comes out first in fractional distillation. fractional distillation is generally used if in boiling point is small.
