Question

Number of lone pairs of electrons on Xe atoms in XeF2, XeF4 and XeF6 molecules are respectively (A) 3, 2 and 1 (B) 4, 3 and 2 (C) 2, 3 and 1 (D) 3, 2 and 0

No. of electrons around Xe in XeF2 = 8 + 2 = 10 Electron pairs =10/2 = 5 Bond pairs = 2 Lone pairs = 5-2 = 3 Similarly, lone pairs in XeF4 = 2 and lone pair in XeF6 = 1

Q. Number of lone pairs of electrons on Xe atoms in $X e F_{2}, X e F_{4}$ and $X e F_{6}$ molecules are respectively

3, 2 and 1

4, 3 and 2

2, 3 and 1

3, 2 and 0

No. of electrons around Xe in XeF2 = 8 + 2 = 10
Electron pairs =10/2 = 5
Bond pairs = 2
Lone pairs = 5-2 = 3
Similarly, lone pairs in $X e F_{4}$ = 2
and lone pair in $X e F_{6}$ = 1
