Winner (-OH)
The OH group is treated as a substituent named _______ when it appears on a structure with a higher priority functional group
hydroxy
alcohols with two -OH groups are called _______. They are named like other alcohols except that the suffix diol is used and 2 numbers are needed to tell where the two hydroxy groups are located
