A

2, 3 and 1

B

1, 2 and 3

C

4, 1 and 2

D

3, 2 and 1

Text Solution

Verified by Experts

(d) Xe-atom has 8 electrons in its outermost shell. In case of `XeF_(2)` out of these 8 electrons, 2 are used for bond formation while 3 pairs remain as such,that's whyit has 3lone pairs
In case of `XeF_(4)`, 4 electrons of Xe are used for bonding, therefore number of lone pairs (non-bonding electrons) is 2. In case of `XeF_(6)`,6 electrons are involed for bond formation, thus number of lone pair is only 1.
