Consider following compounds A to E :
(A) `XeF_(n) " " (B) XeF_((n+1))^(+) " " (C ) XeF_((n+1))^(-) " " (D) XeF_((n+2))`
(E ) `XeF_((n+4))^(2-)`,
If value of n is 4, then calculate value of `p div q` here, 'p' is total number of bond pair and 'q' is total number of lone pair on central atoms of compounds (A) to (E ).

Answer

4
