MULTIPLE CHOICE QUESTION

what happens to the boiling points of alkanes as the number of carbons increase?
boiling point increases
boiling point decreases
boiling point doesn’t change
boiling point increases then decreases
Answer explanation
As the molecules become bigger, the strength of the intermolecular forces of attraction between them increases. This means that more energy has to be put in to break the attractions between one molecule and its neighbours. One effect of this is that the boiling points increase in a regular way.
