​  

H−CH  

3

​  

For IUPAC nomenclature following steps are followed:

1. Identify the fuctional group and their priority: -OH and -Cl are the side groups in the given molecule. OH has higher priority thus the name will have suffix "ol".

2. Identify parent chain: The longest carbon chain that contains the functional group. Here its 6 C chain i.e hexyl

3. Assign locant number: lowest number to the main functional group and side chains i.e. 2-ol  

4. Identify side chains/groups: its chloro, and 5-chloro in the given molecule.
