Question

The common name of 2-Butanone is:

• A. Acetone
• B. Butyraldehyde
• C. Acetic anhydride
• D. Ethyl Methyl Ketone

Hint:

Ketones are named based on the position of the carbonyl group, and common names often use simple functional group names such as “Ethyl Methyl Ketone” for 2-Butanone.

Answer 1

The Correct Option is D

2-Butanone is a common solvent and is also known as Ethyl Methyl Ketone (EMK). This is a ketone with the chemical formula \( C_4H_8O \). The name “Butanone” comes from its structure, which is a butane backbone with a ketone functional group at the second carbon. Therefore, the common name of 2-Butanone is Ethyl Methyl Ketone.
