Verified step by step guidance1
Identify the longest carbon chain that includes the aldehyde group. In this structure, the longest chain is five carbons long, which corresponds to a pentanal.
Number the carbon chain starting from the aldehyde group, which is always at position 1. This ensures the aldehyde group gets the lowest possible number.
Identify and name the substituents attached to the main carbon chain. In this case, there are two methyl groups attached to the second carbon of the chain.
Combine the names of the substituents with the main chain name. Since there are two methyl groups on the second carbon, it is named as 2,2-dimethyl.
Combine the substituent name with the main chain name to get the common name of the aldehyde: 2,2-dimethylpentanal.
