Question

The IUPAC name of \( \text{CH}_3\text{CH}_2\text{OH} \) is:

• A. Ethanol
• B. Methanol
• C. Acetic Acid
• D. Ethanoic Acid

Hint:

In IUPAC naming, alcohols are named by replacing the "e" of the corresponding alkane with "ol." For example: - Ethane → Ethanol - Methane → Methanol

Answer 1

The Correct Option is A

The given chemical formula is \( \text{CH}_3\text{CH}_2\text{OH} \), which is an alcohol. The IUPAC name for this compound is "Ethanol," because it consists of a two-carbon chain (ethane) with a hydroxyl group (\(-OH\)) attached to one of the carbon atoms.
- Methanol (\( \text{CH}_3\text{OH} \)) is a one-carbon alcohol.
- Acetic acid (\( \text{CH}_3\text{COOH} \)) and Ethanoic acid (\( \text{CH}_3\text{COOH} \)) are carboxylic acids, not alcohols.
Thus, the correct IUPAC name for \( \text{CH}_3\text{CH}_2\text{OH} \) is "Ethanol."
