Each name below describes a specific compound. Select the names that are written correctly (lowest locants, alphabetical order, correct principal group).

  1. A4-bromo-2-chlorophenol
  2. B3-carboxytoluene
  3. C3-methylbenzoic acid
  4. D2-chloro-4-bromophenol

Answer: A, C

4-Bromo-2-chlorophenol has prefixes in alphabetical order (bromo before chloro) with lowest locants; 3-methylbenzoic acid uses the acid as the parent. 2-Chloro-4-bromophenol breaks alphabetical order, and 3-carboxytoluene uses the wrong parent because carboxylic acid outranks the methyl-bearing hydrocarbon.
