Number the chain to give the hydroxyl group, -OH, the lowest possible number. That does not mean it will always be number 1. 3. Put the number for the hydroxyl group in front of the parent chain name. Locate and name any other groups. If there is more than one hydroxyl group use diol two triol three Phenols 1.
Phenol is considered to be the parent chain.
The -OH, hydroxyl group, would be number 1 in this case. The names and locations of other groups attached to the ring are placed in front of the phenol. Name the group on either side of the oxygen using the -yl ending. Then add the word ether . If both groups are the same use di in front of the group name.
