Question

What type of compound the aniline is?

• A. \(2^{0}\) and aliphatic
• B. \(1^{0}\) and aliphatic
• C. \(2^{0}\) and aromatic
• D. \(1^{0}\) and aromatic

Hint:

Count the carbon groups on nitrogen and see whether it is attached to a benzene ring.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
An amine is primary if nitrogen is attached to one carbon group, secondary if two. It is aromatic if the nitrogen is bonded directly to a benzene ring.

Step 2: Aniline
Aniline is \(\text{C}_6\text{H}_5\text{NH}_2\). Nitrogen has two hydrogens and one phenyl group.

Step 3: Conclusion
One carbon group means primary. Direct attachment to the ring means aromatic.

Final Answer:
Aniline is a primary aromatic amine. \[ \boxed{\text{(D) }1^{0}\text{ and aromatic}} \]
