Question

# Arrange the following in decreasing order of their boiling points:(1) n-butane (2) $$2$$-methyl butane(3) n-pentane (4) $$2,2$$-dimethyl propane

A
1>2>3>4
B
2>3>4>1
C
4>3>2>1
D
3>2>4>1

Solution

## The correct option is D 3>2>4>1Boiling point is directly proportional to molar mass and surface area . It decreases on branching because surface area decreases. Hence , n-pentane has the highest and n-butane has the lowest boiling points and in rest two branching is there , therefore $$2$$-methyl butane has higher boiling point than $$2,2$$-dimethylpropane. Hence, Option "D" is the correct answer.Chemistry
