    The hybridisation of carbon in molecular \[\text{C}{{\text{O}}_{\text{2}}}\]is

    A) \[sp\]

    B) \[s{{p}^{2}}\]

    C)  \[s{{p}^{3}}\]

    D)  \[s{{p}^{3}}d\]

    Correct Answer: A

    Solution :

     The hybridisation of C in \[\text{C}{{\text{O}}_{\text{2}}}\]molecule is sp. \[C=2,4\](At. number \[=6\]) \[X=\frac{1}{2}\] [valence electrons of central atom +  number of monovalent atoms - charge on cation + charge on anion]                \[=\frac{1}{2}[4+0-0+0]=2\] If \[X=2,\]hybridisation is \[sp.\]
