Which one of the following does not have\[s{{p}^{3}}\] hybridisation?

A)  \[C{{H}_{4}}\]   

B)  \[Xe{{F}_{4}}\]   

C)  \[{{H}_{2}}O\]   

D)  \[N{{H}_{3}}\]

Correct Answer: B

Solution :

 [a] \[C{{H}_{4}}\to \] \[\begin{align}   & =4\sigma \,bond \\  & \Rightarrow s{{p}^{3}}hybridisation \\ \end{align}\] [b] \[Xe{{F}_{4}}\to \] \[=4\sigma \]bond +2 lone pairs \[\Rightarrow \]\[s{{p}^{3}}{{d}^{2}}\]hybridization [c] \[{{H}_{2}}O\to \] \[=2\sigma \]bond + 2 lone pairs \[\Rightarrow \]\[s{{p}^{3}}\]hydridisation [d] \[N{{H}_{3}}\to \] \[=3\sigma \]bond + 1 lone pair \[\Rightarrow \]\[s{{p}^{3}}\]hybridisation
