Question

What effect does branching of an alkane chain has on its boiling point

Answer 1

alkaines experience inter moleculer van der walls forces. it stronger the force the greater will be the boiling point of the alkaine. as branching increases the surface area of the molecule decreases which results in a small area of contact. as a result, van der walls force also decreases which can be overcome at a relatively lower temperature. hence, the boiling point of an alkaine chain decreases with an increase in branching.

Answer 2

Branching of an alkane chain makes the molecules more compact and brings various atoms ... Hence the boiling point of the alkane decreases with branching.
