Question

Consider the three allotropes of carbon :

(i) Diamond
(ii) Graphite
(iii) Fullerenes ($C_{60}$)

The hybridisation state of C-atom in the three allotropes are respectively

• A. $s{p}^2,s{p}^2,s{p}^2$
• B. $s{p}^3,s{p}^2,s{p}^2$
• C. $s{p}^3,s{p}^3,s{p}^3$
• D. $s{p}^3,s{p}^2,s{p}^3$

Answer 1

The correct option is B $s{p}^3,s{p}^2,s{p}^2$

Hybridisation of C in graphite is $s{p}^2$.

Hybridisation of C in $C_{60}$ is $s{p}^2$.
