Question

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

• 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 C

The molecular formula \( \text{CH}_3\text{CH}_2\text{CH}_2\text{OH} \) corresponds to an alcohol with three carbon atoms, making it propanol. The functional group \(-\text{OH}\) confirms it is an alcohol. Thus, the correct IUPAC name for the compound is propanol, corresponding to option (3).
