IUPAC name of CH\(_3\)CHO is:

• A. Ethanol.
• B. Acetaldehyde.
• C. Propanol.
• D. Butanal.

Hint:

Ethanol is a common alcohol, and its IUPAC name is based on its structure and functional group. The correct IUPAC name for CH\(_3\)CHO is ethanol.

Answer 1

The Correct Option is A

Step 1: Understanding the structure.
The given compound CH\(_3\)CHO is an aldehyde group (–CHO) attached to a methyl group (–CH\(_3\)). Step 2: IUPAC naming.
The IUPAC name for CH\(_3\)CHO is ethanol because the compound consists of two carbon atoms and the functional group is an aldehyde. Step 3: Explanation.
According to IUPAC nomenclature, aldehydes are named by replacing the "-e" from the parent alkane name with "-al." Since CH\(_3\)CHO is derived from ethane, the IUPAC name is ethanol. Step 4: Conclusion.
Thus, the IUPAC name of CH\(_3\)CHO is ethanol.
