Check what you remember
Read the wording for your board, then hide it and explain Effect of branching on boiling point in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
A more branched isomer has a smaller surface area for contact between molecules, so the London forces are weaker and the boiling point is lower than that of its straight-chain isomer.
