What is the hybridisation of carbon atoms in fullerene ?

Options

A. `sp^(3)`
B. `sp`
C. `sp^(2)`
D. `dsp^(3)`

Answer

C

Explanation

Fullerenes are the allotropes of carbon also called Buckminster fullerenes.
They are cage like spheroidal molecules with general formula, `C_(2n)` (e.g, `C_(60), C_(70)` etc).
`C_(60)` or the bucky ball consists of 60 C- atoms arranged in 20 six membered and 12 five appearance of a soccer ball.
Each C-atom in `C_(60)` in `sp^(2)`-hybridised forming `sigma`-bonds with three other C-atoms . The fourth electron remains free and responsible for its conductivity .
