Q.
What is the correct $IUPAC$ name of the compound shown below?
Organic Chemistry – Some Basic Principles and Techniques
Solution:
—CN has higher priority than —OH group, hence the phenyl ring containing —CN is the parent ring. In the locant ring, both —OH and —Br are equidistant from the branch point, hence numbering is done in alphabetical order giving lower number to bromo substituent as:
3-(3-bromo-5-hydroxyphenyl) benzonitrile
