Question

Identify the IUPAC name of the compound.

• A. Cyclobutanol
• B. 2-Methoxypropane
• C. 2-Methylcyclobutanol
• D. 2-Hydroxyethylcyclopentane

Hint:

Choose the ring as the parent, give the -OH group locant 1 and number toward the methyl substituent.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
In IUPAC naming, the principal functional group (-OH) gets the suffix 'ol' and the lowest locant. Other groups are prefixes.

Step 2: Parent chain
The ring has four carbons, so the parent is cyclobutane, giving cyclobutanol.

Step 3: Numbering
The ring carbon with -OH is C-1. The methyl group is on the adjacent ring carbon, which is C-2.

Step 4: Name
The compound is 2-methylcyclobutan-1-ol, written as 2-methylcyclobutanol.

Final Answer:
The IUPAC name is 2-methylcyclobutanol. \[ \boxed{\text{(C) }\text{2-Methylcyclobutanol}} \]
