Aldehyde vs Ketone. Aldehydes and ketones are known as organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen. The carbonyl carbon atom is sp2 hybridized. So, aldehydes and ketones have a trigonal planar arrangement around the carbonyl carbon atom. The carbonyl group is a polar group, thus, aldehydes and ketones have higher boiling points compared to the hydrocarbons having the same weight.
