Question

give a reason why n-butyl bromide has higher bolingpoint than t-butyl bromide.

Answer 1

The boiling point of n-butyl bromide is higher than t-butyl bromide, as because of the intermolecular forces between the molecule is higher.
so it not easily broken the molecule.
I hope this answers will satisfy you.
Thanks.

Answer 2

Hey !!

n-Butyl bromide being a straight chain alkyl halide has larger surface area than tert. butyl bromide. Larger the surface area, larger the magnitude of the van der Waal's forces and hence higher is the boiling point.

Good luck !!
