Give IUPAC name of the compound given below.(i) 2-Chloro-5-hydroxyhexane (ii) 2-Hydroxy-5-chlorohexane (iii) 5-Chlorohexan-2-ol (iv) 2-Chlorohexan-5-ol
Give IUPAC name of the compound given below.(i) 2-Chloro-5-hydroxyhexane (ii) 2-Hydroxy-5-chlorohexane (iii) 5-Chlorohexan-2-ol (iv) 2-Chlorohexan-5-ol

Option (iii) is the answer.

We begin by choosing the longest carbon chain in the supplied organic molecule, as defined by IUPAC nomenclature. We use hexane because the longest carbon chain has six members. According to IUPAC, alcohols (–OH) take precedence over halogens (-Chloro here). So, we’ll begin identifying the chain from the –OH side.
