Answer to Question #120491 in Organic Chemistry for Fadi Geogre

Question

Although butane has 4 carbon atoms, its boiling point is lower than compounds that have 3
carbon atoms, Illustrate why?

Answer 1

The lower boiling point is a result of the more compact structure of the butane forming isomer, which has less surface area than the straight-chain isomer, and thus fewer London forces between its molecules
