Naming a ring with an alcohol group?
It depends on the priority of the substituents on the ring. If the highest-priority group is the alcohol group, then the numbering of the carbons in the ring starts there - so the 1 is implicit, and you do not need to state it. See 2-(3-Methylbutyl)cyclohexanol as an example.



Note that the alkyl group position is assigned a number relative to the position of the -OH group. However, if there is a higher-priority group than -OH then the position of the alcohol will be assigned a number relative to this higher-priority group; see 2-hydroxy-3-chlorobenzoic acid.



In your example, the 1 is not necessary.
