In\[Xe{{O}_{3}}{{F}_{2}}\], the number of bond pair(s), \[\pi -\]bond(s) and lone pair(s) on Xe atom respectively are. [JEE Online 15-04-2018 (II)]

A)         \[5,3,0\]                              

B) \[5,2,0\]              

C) \[4,2,2\]              

D)          \[4,4,0\]

Correct Answer: A

Solution :

In \[Xe{{O}_{3}}{{F}_{2}}\], the number of bond pair(s), \[\pi -\]bond(s) and lone pair(s) on Xe atom are \[5,3,0\]respectively. There are three \[Xe=O\] double bonds and two \[Xe-F\]single bonds. All the valence electrons of Xe are involved in bonding.
