Question

Why do cycloalkanes have a higher boiling point than alkanes?

Answer 1

This is because they have strong bond with each other that requires a high temperature to break down so the cycloalkanes have higher melting point than alkanes

Answer 2

Why alcohol have higher boiling point than corresponding alkanes?

Because Hydrogen bonds are much stronger than these.

Therefore, more energy is required to separate alcohol molecules than to separate alkane molecules.
