Among the following molecules(i) ${\text{XeO}}_3$ (ii) ${\text{XeOF}}_4$ (iii) ${\text{XeF}}_6$ Those having same number of lone pairs on $\text{Xe}$ are:

Xe has 8 valence electrons.${\text{XeO}}_3$: Uses 6 electrons for 3 double bonds with O. Remaining = 2 electrons (1 lone pair).${\text{XeOF}}_4$: Uses 2 electrons for O and 4 for F. Remaining = 2 electrons (1 lone pair).${\text{XeF}}_6$: Uses 6 electrons for 6 bonds with F. Remaining = 2 electrons (1 lone pair).All three have exactly one lone pair on the Xenon atom.
