1.	How would you account for the following :The boiling points of aldehydes and ketones are lower than of the corresponding acids.
Answer» The boiling points of aldehydes and ketones are lower than that of corresponding alcohols and acids due to absence of intermolecular H–bonding in aldehydes and ketones.
