According to IUPAC nomenclature, we start by selecting the longest Carbon chain in the given organic compound.

Here, the longest carbon chain is of 6 members, so we use hexane. (–OH) Alcohols are given priority over halogens (-Chloro here) according to IUPAC. So, here we start naming the chain from –OH side .

Combining these, we name the given organic compound as:

5-Chlorohexan-2-ol
