The correct order of boiling points of 2, 2-dimethylpropane, 2 methylbutane and n pentane is

A

n-pentane gt 2,2-dimethylpropane gt 2-methyl-butane

B

n-pentane gt 2-methylbutane gt 2,2-dimethyl-propane

C

2-methylbutane gt n-pentane gt 2,2-dimethyl-propane

D

2-methylbutane gt 2 ,2-dimethylpropane gt n-pentane

Text Solution

Verified by Experts

The correct Answer is:
B
Boiling point decreases as branching increases, i.e., n-pentane gt 2-methylbutane gt 2,2-dimethyl-propane
