Question:
Which of the allotropic forms of carbon is aromatic in nature?
Which of the allotropic forms of carbon is aromatic in nature?
Show Hint
Graphite has delocalized π-electrons in layers, making it aromatic in nature.
Updated On: Mar 24, 2025
- Diamond
- Graphite
- Buckminster fullerene
- Coke

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding Aromaticity
A compound is aromatic if it has:
- A planar conjugated π-system
- Delocalized \( 4n+2 \) π-electrons (Hückel’s rule)
Step 2: Analyzing Allotropes of Carbon
- Diamond: 3D network, no delocalized electrons
- Graphite: Layered structure, delocalized π-electrons
- Buckminster fullerene: Curved structure, not fully delocalized
- Coke: Amorphous carbon, no defined conjugation
Thus, Graphite is aromatic.
