Question

Branched chain alkanes have lower boiling points. It is true.​

Answer 1

Answer:

the intermolecular forces that is based on surface area is low and so the branched chain alkanes have lower boiling points than straight chain alkanes

Answer 2

Branched chain alkanes have lower boiling point because the increase in number of branches gives the molecule a spherical shape which results in smaller area of contact which decreases the boiling point

This is given in page 380 class 11 chemistry part 2
