Which of the following has highest boiling point?

A$$1$$-chloropentane
Correct Answer
B$$2$$-chloropentane
C$$3$$-chloropentane
DAll have equal boiling point

Solution

$$2-chloropentane$$ is branched. So, its surface area is lower than that of $$1-chloropentane$$. If surface area decreases the ability of molecules to interact through vanderwaal forcesdecrease, so the boiling point decreases.
So, $$1-chloro-pentane$$ has highest boiling point.
