Two liquids isohexane and 3-methylpentane has boiling point 60°C and

1.	Two liquids isohexane and 3-methylpentane has boiling point 60°C and 63°C. They can be separated by (1) Simple distillation and isohexane comes out first. (2) Fractional distillation and isohexane comes out first. (3) Simple distillation and 3-Methylpantane comes out first. (4) Fractional distillation and 3-Methylpantane comes out first.
Answer» Answer: (2) Fractional distillation and isohexane comes out first. Liquid having lower boiling point comes out first in fractional distillation. Simple distillation can't be used as boiling point difference is very small.
