    Atomic orbitals of carbon in carbon dioxide are

    A)  \[s{{p}^{2}}-\]hybridised            

    B)  \[s{{p}^{3}}d-\]hybridized         

    C)  \[sp\]-hybridised           

    D)  \[s{{p}^{3}}-\]hybridised.

    Correct Answer: C

    Solution :

    \[{{C}_{ached\text{ }state}}=2{{s}^{1}}2{{p}_{x}}^{1}{{p}_{y}}^{1}{{p}_{z}}^{1}\] \[{{O}_{ground\text{ }state}}=2{{s}^{2}}2{{p}_{x}}^{2}{{p}_{y}}^{1}{{p}_{z}}^{1}\] In the formation of \[C{{O}_{2}}\] molecule, hybridization of orbitals of carbon occurs only to a limited extent involving only one s and one p orbital and gives rise to \[sp\] hybridization.
