Number from the hydroxyl carbon.

Explanation:

When such phenyl compounds are named as phenol derivatives, the carbon bound to hydroxide AUTOMATICALLY becomes no. #"1"#. There are 5 other positions on the phenyl ring that can be substituted: #"2"#; #"3"#; #"4"#; #"5"#; and #"6"#. If a bromide substituted directly next to the phenol (i.e. ortho to the ipso carbon), it would be numbered as #"2"#, rather than as #"6"#. The next carbon along the chain is #"3"#, then #"4"# etc.

You will have to check in your text for pictures.
