A benzene ring bears an -OH group (C-1), a methyl group ortho to it and a chlorine atom para to it. The IUPAC name is

  1. A2-chloro-4-methylphenol
  2. B4-chloro-6-methylphenol
  3. C2-methyl-4-chlorophenol
  4. D4-chloro-2-methylphenol

Answer: D

Phenol is the parent with OH at C-1. The substituents sit at 2 (methyl) and 4 (chlorine), giving the lowest set {2,4} (not {4,6}). Prefixes are alphabetical: chloro before methyl. The name is 4-chloro-2-methylphenol.
