Question 26
Which compound is an amide? A. CH₃CH₂CH₂CN B. CH₃CONHCH₂CH₃ C. CH₃COOCH₃ D. CH₃N(CH₂CH₃)₂
Worked Solution & Example Answer:Which compound is an amide? A - AQA - A-Level Chemistry - Question 26 - 2022 - Paper 3
Step 1
Identify the amide compound
Answer
An amide is a compound that contains a carbonyl group (C=O) directly attached to a nitrogen atom (N).
Among the given options:
- A. CH₃CH₂CH₂CN is a nitrile, not an amide.
- B. CH₃CONHCH₂CH₃ contains a carbonyl group (C=O) attached to a nitrogen (N), making it an amide.
- C. CH₃COOCH₃ is an ester, not an amide.
- D. CH₃N(CH₂CH₃)₂ does not have a carbonyl group, thus it is not an amide.
Therefore, the correct answer is B: CH₃CONHCH₂CH₃.
