Question

Arrange the following compounds in the increasing order of their boiling points.
acetone, n—propyl alcohol, ethyl methyl ether and n—butane.

Answer 1

For any question...just learn the series...

Acid>alcohol>aldehyde>ketone>ether>hydrocarbon

Using this...

n-propyl-alcohol > acetone > ethyl methyl ether > n-butane

Answer 2

Hello dear,

◆ Answer -
Increasing order of their boiling points for given options is -
n-butane < ethyl methyl ether < acetone < n-propyl alcohol

● Explanation -
- All these given compounds have comparable molecular masses, so their boiling boints are influenced by type of intermolecular forces present in them.
- Boiling points of various types of compounds varies as -
alkane < ether < ketone < aldehyde < alcohol < carboxylic acids
- Increasing order of their boiling points for given options is -
n-butane < ethyl methyl ether < acetone < n-propyl alcohol


Hope this helped you. Thanks for asking...
