Quizplus · Accepted Answer

The correct IUPAC name for a compound initially named as 2,2-diethylpentane would be 3-ethyl-3-methylhexane. This is because the longest carbon chain actually has six carbons (hexane), and the substituents are an ethyl and a methyl group, both located on the third carbon of the chain.
