검증된 단계별 안내1
Identify the main carbon chain in the compound name '4-ethyl-3,6-dimethyldecane'. The suffix '-decane' indicates a 10-carbon chain, which is characteristic of an alkane.
Determine the substituents attached to the main carbon chain. The name '4-ethyl-3,6-dimethyldecane' indicates three substituents: an ethyl group at carbon 4 and two methyl groups at carbons 3 and 6.
Verify the numbering of the carbon chain. The substituents are numbered to give the lowest possible numbers, which is consistent with the IUPAC naming rules.
Count the total number of substituents. In this case, there are three substituents: one ethyl and two methyl groups.
Conclude that the compound is an alkane with three substituents attached to a 10-carbon chain, which matches the correct answer provided.
