What is the IUPAC name of the branched alkane with structural formula (CH3)2CH-CH2-CH(CH3)2?
Answer and explanation
Correct answer: C. 2,4-dimethylpentane
The longest continuous carbon chain has 5 carbons (pentane). Numbering from either end gives methyl substituents at positions 2 and 4, yielding 2,4-dimethylpentane.
