Question

Which of the following represents the correct IUPAC name for \( \text{CH}_3\text{CH}_2\text{OH} \)?

• A. Methanol
• B. Ethanol
• C. Propanol
• D. Butanol

Hint:

Alcohols are named by identifying the longest carbon chain and adding the suffix -ol to the name.

Answer 1

The Correct Option is B

The molecular formula \( \text{CH}_3\text{CH}_2\text{OH} \) represents ethanol, an alcohol characterized by its two carbon atoms and the \(-\text{OH}\) functional group. The IUPAC nomenclature for this compound is Ethanol. Thus, option (2) is the correct selection.
