IUPAC name of trisubstituted benzene ring What is the IUPAC name for the compound shown below? I named it as 6-Bromo-3-hydroxy benzonitrile according to the numbering scheme in 1b, since the priority order is $\ce{-CN} &gt; \ce{-OH} &gt; \ce{-Br}$.

However, the answer given in the book is 2-Bromo-5-hydroxy benzonitrile, which implies the numbering scheme in 1a. Please help me to identify whether my answer or the book's answer is correct.
As -CN has the highest priority, root-word is benzonitrile. Lowest locant is 2 for -Br.
So, the name given is:
2-bromo-5-hydroxybenzonitrile

As the functional group is -CN, with highest priority, no need to look for priority of -OH and -Br; just look for lowest locant.
