    What type of orbital hybridisation is considered on P in \[PC{{l}_{5}}\]?

    A)  \[s{{p}^{3}}d\]                                

    B)  \[ds{{p}^{3}}\]

    C)  \[s{{p}^{3}}{{d}^{2}}\]                 

    D)  \[{{d}^{2}}s{{p}^{3}}\]

    Correct Answer: A

    Solution :

                     In \[\text{PC}{{\text{l}}_{\text{5}}}\text{,}\]number of hybrid orbitals,\[H=\frac{1}{2}[V+x+A-C]\] [where, V = number of valence electrons X = number of monovalent atoms A and C = charge of cation or anion] \[H=\frac{1}{2}[5+5+0-0]\]          \[=5\] Thus, the hybridisation is \[s{{p}^{3}}d.\]
