Among the following compounds the one that is polar and has the central atom with \[~s{{p}^{2}}\] hybridization is

A) \[{{H}_{2}}C{{O}_{3}}\]    

B) \[Si{{F}_{4}}\]

C) \[B{{F}_{3}}\]                         

D) \[HCl{{O}_{2}}\]

Correct Answer: A

Solution :

[a] \[{{H}_{2}}C{{O}_{3}}\]and \[B{{F}_{3}}\] both have triangular planar \[B{{F}_{3}}\] is symmetrical \[\therefore \,\mu =0\] hence non polar, \[{{H}_{2}}C{{O}_{3}}\] is not symmetrical hence polar in nature.
