Arrange the following compounds in increasing order of boiling point.
The answer is the option (i). To find out the order of boiling point in alcohols, the important factor is molecular mass. With an increasing molecular mass of the compound, the boiling point also increases. So, the compound with a maximum boiling point will be pentan-1-ol, and the compound with the least boiling point is Propan-1-ol.
The correct order would be Option (i)
