In `XeF_(2),XeF_(4)` and `XeF_(6)(g)` the number of lone pairs on Xe respectively are :A. 2,3,1B. 1,2,3C. 4,1,2D. 3,2,1 |

Answer» Correct Answer - 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 remains such , i.,e it has 3 lone pair. In case of `XeF_(4),4` electrons of Xe are used for bonding. Therefore, number of lone pairs (non-bonding electrons) is 2. In cae of `XeF_(6),6` electrons are involved for bond formation, thus, number of lone pair is only one. |
