Provide the systematic name for the following alcohol.

• A. 1-methyl-1-hydroxycyclohexane
• B. 1-methylcyclohexanol
• C. 1-methyl-1-hydroxyhexane
• D. 1-methylhexanol

Answer: (B)

Verified step by step guidance

1. Identify the parent hydrocarbon chain or ring. In this case, the structure is a cyclohexane ring, which is a six-membered carbon ring.
2. Locate the functional group with the highest priority. Here, the functional group is the hydroxyl group (-OH), which defines the compound as an alcohol.
3. Number the ring to give the hydroxyl group the lowest possible number. Since the -OH group is attached to carbon 1, it is numbered as such.
4. Identify and name any substituents attached to the ring. There is a methyl group attached to the same carbon as the hydroxyl group (carbon 1).
5. Combine the names by placing the substituent name before the parent name and using the suffix '-ol' for the alcohol. The correct systematic name is 1-methylcyclohexanol.
