(iii) `H_(3)C-underset(Br)underset(|)overset(CH_(3))underset(|)C-CH_(3)`

A

`(ii)lt(i)lt(iii)`

B

`(iii)lt(ii)lt(i)`

C

`(iii)lt(i)lt(ii)`

D

`(iii)lt(ii)lt(i)`

Text Solution

Verified by Experts

The correct Answer is:
C
Boiling point of a compound depends upon the surface area. Higher the surface area higher will be the boiling point of a compound. Surface area decreases with increase in branching. If the compound has branching so its boiling point will be minimum.
Thus, the increasing order of their boiling points
