This document discusses the nomenclature and properties of alcohols, aldehydes, and ketones. It explains that alcohols contain an -OH functional group and are named by replacing the -e with -ol. Aldehydes have a C=O group at the end of the carbon chain and are named by replacing -e with -al, while ketones have a C=O group within the chain and use -one. Alcohols have higher boiling points than hydrocarbons due to hydrogen bonding, while aldehydes and ketones have lower boiling points without hydroxyl groups.
