Q8 / 60 · JEE Advanced 2009 (Paper 1) · Chemistry

The IUPAC name of the following compound, is

A
4-bromo-3-cyanophenol
Correct answer
B
2-bromo-5-hydroxybenzonitrile
C
2-cyano-4-hydroxybromobenzene
D
6-bromo-3-hydroxybenzonitrile

Solution

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

Hence, the correct answer is option: 'B'.
