Determine the correct IUPAC name for the organic compound with the skeletal structure: — Haloalkanes and Haloarenes Chemistry Question

💡 Solution & Explanation

The selection of the parent chain and numbering is governed by IUPAC rules: 1. The longest continuous carbon chain containing the maximum number of substituents is selected. Here, the aliphatic chain has 4 carbons (butane). 2. Numbering must give the lowest possible locants to the substituents. Numbering from right to left gives substituents at C1 (bromo, phenyl) and C3 (dimethyl). The locant set (1, 1, 3, 3) is lower than the set obtained from left to right (2, 2, 4, 4). 3. Substituents are listed in alphabetical order: Bromo, then dimethyl (ignoring the 'di' prefix for alphabetization, so 'm'), then phenyl. Following these rules, the correct IUPAC name is 1-bromo-3,3-dimethyl-1-phenylbutane.
