Question Detail
Question
Which of the following is a correct name according to the IUPAC rules?
Correct Answer
Option D is the correct answer.
Detailed Explanation
3-Ethyl-2-methylpentane is correctly named according to IUPAC rules. 2-Methylcyclohexane needs a locant for the methyl group (it should be methylcyclohexane or 1-methylcyclohexane). 2-Ethyl-2-methylpentane has an incorrect longest chain. 3,4-Dimethylpentane should be 2,3-dimethylpentane (lowest locants).
Hint
Check for the correct parent chain and lowest locants in each name.
