A flask contains a mixture of isohexane and 3 -methylpentane. One of the liquids boils at 63oC while the other boils at 60oC. What is the best way to separate the two liquids and which one will be distilled out first?
  1. fractional distillation, isohexane
  2. simple distillation, 3 -methylpentane
  3. simple distillation, isohexane
  4. fractional distillation, 3 -methylpentane

Solution

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