JEE MAIN - Chemistry (2020 - 8th January Morning Slot - No. 19)
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 ?
fractional distillation, 3-methylpentane
simple distillation, 3-methylpentane
fractional distillation, isohexane
simple distillation, isohexane
Explanation
Isohexane and 3 Methylpentane Having same molecular formula.
Isohexane boil at 60oC and 3-Methyl pentane boil at 63oC. Both Having low Boiling point difference so Fractional distillation is useful for separation and Isohexane Having low Boiling point So comes out first.
