The IUPAC name of the following compound, is

Options

  1. A4-bromo-3-cyanophenol
  2. B2-bromo-5-hydroxybenzonitrile
  3. C2-cyano-4-hydroxybromobenzene
  4. D6-bromo-3-hydroxybenzonitrile

Correct answer

B. 2-bromo-5-hydroxybenzonitrile

Step-by-step solution

Cyano group has the highest priority therefore, parent name must be benzonitrile. Br occurs at 2-position, and hydroxyl at 3-position, hence clockwise numbering will be the correct one.
