The linear shape of `CO_(2)` is due to ……….

Options

A. `sp^(3)` hybridisation of carbon
B. sp hybridisation of carbon
C. `p pi - p pi` bonding between carbon and oxygen
D. `sp^(2)` hybridisation of carbon

Answer

B, C

Explanation

Sigma bond formed by s-s overlap, s-p overlap and p-p overlapping, pi `(pi)` bond formed by p-p overlapping.
The structure of `CO_(2)` is
`{:(p-p(pi),p-p(pi)),(O=C,=O),(sp-p(sigma),sp-p(sigma)):}` is 2 sigma bonds and 2 pi bonds
Hybridisation of `CO_(2)` is sp and the shape is linear. Due to pi bond, it is `p pi - p pi` bonding between carbon and oxygen.
