                Trigonal bipyramidal geometry is shown by:     JEE Main Online Paper (Held On 09 April 2013)              

A)                 \[\operatorname{X}e{{\operatorname{OF}}_{2}}\]                

B)                 \[\operatorname{X}e{{\operatorname{O}}_{3}}{{F}_{2}}\]                

C)                 \[\operatorname{F}\operatorname{X}e\operatorname{O}{{\operatorname{SO}}_{2}}\operatorname{F}\]                

D)                 \[{{\left[ \operatorname{X}\operatorname{e}{{\operatorname{F}}_{8}} \right]}^{2-}}\]                

Correct Answer: B

Solution :

                Trigonal bipyramidal geometry is shown by \[Xe{{O}_{3}}{{F}_{2}}\].                       Hybridization on Xe atom,                 \[H=\frac{1}{2}(V+M-C+A)=\frac{1}{2}(8+2-0+0)\]                 \[=\frac{10}{2}=5=s{{p}^{3}}d\]                 Trigonal bipyramidal geometry.                                 Structure of \[Xe{{O}_{3}}{{F}_{2}}\] molecule
