Question

A medicine compound having an amide linkage was asked. Which of the following compounds contains an amide linkage?

• A. Acetanilide
• B. Aspirin
• C. Benzene
• D. Acetic acid

Hint:

An amide functional group consists of a carbonyl group (\( -\text{CO} \)) bonded to a nitrogen atom (\( \text{NH}_2 \)). Recognizing this structure can help identify compounds containing amides.

Answer 1

The Correct Option is A

An amide linkage is a functional group represented by the general formula \( -\text{CO}-\text{NH}_2 \). This group comprises a carbonyl group (\( \text{C=O} \)) bonded to a nitrogen atom (\( \text{NH}_2 \)).
Step 1: Compound Identification (Amide Group Presence)- Acetanilide: Contains the amide functional group. Its structure involves an aniline moiety linked to an acetyl group (\( \text{C=O}-\text{CH}_3 \)) via an amide bond.- Aspirin: Possesses an ester linkage, not an amide. It features a carboxyl group and an ester functional group.- Benzene: A hydrocarbon lacking any functional groups, including amide.- Acetic acid: Contains a carboxyl group (\( -\text{COOH} \)), not an amide.
Step 2: DeterminationBased on the preceding analysis, Acetanilide is identified as containing an amide linkage.Consequently, the correct answer is \( \boxed{\text{Acetanilide}} \).
