Subjective Type

Arrange the following in order of increasing boiling points n-hexyl chloride , n-pentyl chloride , tert-butyl chloride , n-propyl chloride , sec-butyl chloride.

Solution

As the length of the carbon chain increases, the boiling point increases and amongst isomeric alkyl halides, boiling point decreases as the branching increases.

Thus, n-hexyl chloride with six carbon atoms has the highest b.p. followed by n-pentyl chloride with five carbon atoms followed by sec-butyl chloride and tert-butyl chloride with four carbon atoms each followed by n-propyl chloride with three carbon atoms.

Amongst sec butyl chloride and tert-butyl chloride, tert-butyl chloride has lower boiling point because of two branches than sec-butyl chloride with no branching.

Thus, the overall order is:
n-hexyl chloride > n-pentyl chloride > sec-butyl chloride > tert-butyl chloride > n-propyl chloride.
