Question
Find the position (locant number) of the complex substituent in the correct IUPAC name of the compound: $CH_3-CH_2-CH_2-CH_2-CH(CH(CH_3)_2)-CH_2-CH_2-CH_2-CH_3$.
Answer: 5
💡 Solution & Explanation
The principal carbon chain contains 9 carbon atoms (nonane). The substituent is a 1-methylethyl (isopropyl) group attached to the central carbon. Numbering from either end of this symmetrical 9-carbon chain places the complex substituent strictly at carbon 5.
