Which one of the following compounds has  \[\text{s}{{\text{p}}^{\text{2}}}\] hybridisation?

A) \[C{{O}_{2}}\]                   

B)        \[S{{O}_{2}}\]   

C)  \[{{N}_{2}}O\]                 

D)         \[CO\]

Correct Answer: B

Solution :

In \[\text{S}{{\text{O}}_{\text{2}}}\]molecule, S is \[\text{s}{{\text{p}}^{2}}\] \[-\]hybridized    \[S(16)=1{{s}^{2}},2{{s}^{2}}2{{p}^{6}},3{{s}^{2}},3{{p}^{4}}\] Note \[C{{O}_{2}},{{N}_{2}}O\]and CO, all are sp-hybridised.
