At $143 K,$ the reaction of $X e F_{4}$ with $O_{2} F_{2}$ produces a xenon compound $Y .$ The total number of lone pair(s) of electrons present on the whole molecule of $Y$ is __________

Answer:

19.00

Solution:

${XeF}_{4} + O_{2} F_{2} \to {XeF}_{6} + O_{2}$

So $Y$ is ${XeF}_{6}$

Each $F$ atom contains three lone pairs and $Xe$ atom contain one lone pair.

so total lone pair $= 3 \times 6 + 1 = 19$

Total $L . P = 19$ .
