The properties of alcohols and phenols are chiefly due
to the hydroxyl group The nature of alkyl and aryl groups simply
modify these properties Boiling Points
The boiling points of alcohols and phenols increase with increase in the
number of carbon atoms (increase in van der Waals forces) In alcohols,
the boiling points decrease with increase of branching in carbon chain
(because of decrease in van der Waals forces with decrease in surface
area)
