The IUPAC name of the compound

(A)3, 3- dimethyl -1- hydroxy cyclohexane
(B)1,1-dimethyl -3- cyclohexanol
(C)3,3- dimethyl -1- cyclohexanol✓ Correct
(D)1,1 - dimethyl -3- hydroxy cyclohexane

Answer: (C)

Solution

Name the ring from its principal group. The hydroxyl takes priority and is given position 1, then the ring is numbered to keep the substituent locants as low as possible, placing the two methyl groups together at carbon 3. That gives 3,3-dimethyl-1-cyclohexanol, equally written 3,3-dimethylcyclohexan-1-ol.
