The IUPAC name of HOCHX2−CHX2−CH(Cl)−CH(CHX3)−CHX2−CHX3 is:
A4-chloro-3-methylhexan-1-ol
B3-chloro-4-methylhexan-6-ol
C4-methyl-3-chlorohexan-1-ol
D3-chloro-4-methylhexan-1-ol
Answer: D
The longest chain has six carbons and the OH carbon must be C-1. Chlorine is then on C-3 and the methyl on C-4. Prefixes are cited alphabetically, chloro before methyl, giving 3-chloro-4-methylhexan-1-ol.
