Question

Which of the following compounds is NOT a carbonyl compound?

• A. Propanamide
• B. Ethoxy ethane
• C. Acetamide
• D. Acetyl chloride

Hint:

Carbonyl compounds contain the C=O group, which is absent in ethers like ethoxy ethane.

Answer 1

The Correct Option is B

Step 1: Understanding carbonyl compounds.
Carbonyl compounds are compounds that contain a carbonyl group (C=O). This group is present in aldehydes, ketones, carboxylic acids, and their derivatives. Ethoxy ethane is an ether and does not contain a carbonyl group.
Step 2: Analyzing the options.
(A) Propanamide: Incorrect. Propanamide is a carbonyl compound as it contains the carbonyl group (C=O) in an amide.
(B) Ethoxy ethane: Correct. Ethoxy ethane (also known as diethyl ether) is an ether, not a carbonyl compound.
(C) Acetamide: Incorrect. Acetamide is a carbonyl compound, as it contains the carbonyl group (C=O) in an amide.
(D) Acetyl chloride: Incorrect. Acetyl chloride is a carbonyl compound, as it contains the carbonyl group (C=O) in an acyl chloride.
Step 3: Conclusion.
The correct answer is (B) Ethoxy ethane, which is not a carbonyl compound.
