Give reasons
n-butyl bromide has higher boiling point than tert-butyl bromide.

Explanation

For isomeric alkyl halides, the boiling point decreases with branching because with branching, the surface area of the alkyl halide decreases and hence,the magnitude of van der Waals. forces of attraction decreases. Therefore, n-butyl bromide `(CH_(3)CH_(2)CH_(2)CH_(2)Br)` has higher boiling point than tert-butyl bromide.
