According to VSEPR theory, the molecule that has T-shape is

A) \[CI{{F}_{3}}\]                                  

B) \[N{{H}_{3}}\]

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

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

Correct Answer: A

Solution :

                \[CI{{F}_{3}}\Rightarrow 3bp+2lp,\] ie,\[s{{p}^{3}}d\]hybridisation The shape of\[CI{{F}_{3}}\]should be trigonal bipyramidal but presence of two lone pairs converts it into T-shape. (The shape of\[N{{H}_{3}}\]is pyramidal,\[{{H}_{2}}O\]is angular and that of\[B{{F}_{3}}\]is trigonal planar.)
