Detailed explanation-1: -This compound has the carbonyl group on an end carbon atom, so it is an aldehyde. This compound has the carbonyl group on an interior carbon atom, so it is a ketone. Both alkyl groups are propyl groups. The name is therefore dipropyl ketone.
Detailed explanation-2: -the carbonyl group is located within the carbon skeleton (meaning that the carbonyl carbon is bonded to two other carbons in addition to its double bond with oxygen). Sugars containing 1 ketone group: ketoses. Ex: ribose is an aldose, and ribulose is a ketose. ranges from 3-7.
Detailed explanation-3: -So, a ten-carbon chain containing a C=O. group at the end is called decanal. It is an aldehyde, because, being at the end of the chain, the carbonyl carbon is attached to one carbon and one hydrogen.
