Verified step by step guidance1
Identify the functional group present in the compound. The structure shows an ester functional group, characterized by the carbonyl group (C=O) adjacent to an ether linkage (O-C).
Determine the alkyl group attached to the oxygen atom of the ester. In this structure, a cyclopentyl group is attached to the oxygen atom, which is a five-membered carbon ring.
Identify the carbon chain attached to the carbonyl carbon. The chain consists of four carbon atoms, which corresponds to a butyrate group.
Examine the substituents on the carbon chain. There are two methyl groups attached to the second carbon of the butyrate chain, making it a 4,4-dimethyl substitution.
Combine the identified parts to name the compound. The name is derived from the alkyl group attached to the oxygen (cyclopentyl) and the modified carboxylic acid chain (4,4-dimethyl valerate), resulting in the name cyclopentyl 4,4-dimethyl valerate.
