검증된 단계별 안내1
Identify the longest continuous carbon chain in the structure. Since the problem states a six-carbon chain, the parent name will be 'hexane'.
Number the carbon chain from the end nearest to the first substituent to give the substituents the lowest possible numbers. Here, you have a methyl group on carbon 2 and a bromine atom on carbon 4.
Assign the substituents their correct locants based on the numbering. The methyl group is at carbon 2, and the bromo substituent is at carbon 4.
List the substituents in alphabetical order when writing the name, regardless of their position numbers. 'Bromo' comes before 'methyl' alphabetically.
Combine the substituents and parent name into the full IUPAC name, placing the substituents with their numbers and separating multiple substituents with hyphens and commas as needed, resulting in the format: \(4\)-bromo-\(2\)-methylhexane.
