Question:
The IUPAC name of \( \text{CH}_3\text{CH}_2\text{OH} \) is:
The IUPAC name of \( \text{CH}_3\text{CH}_2\text{OH} \) is:
Show Hint
In IUPAC naming, alcohols are named by replacing the "e" of the corresponding alkane with "ol." For example:
- Ethane → Ethanol
- Methane → Methanol
Updated On: Oct 10, 2025
- Ethanol
- Methanol
- Acetic Acid
- Ethanoic Acid
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
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."
- 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."

- Chemical Properties Of Carbon Compounds
- More than three million carbon compounds have been discovered in the field of chemistry. The diversity of these compounds is due to the capacity of carbon atoms for bonding with one another as well as with other atoms. Most of the carbon compounds are poor conductors of electricity and have low melting and boiling points.
