Amongst the following which one will have maximum 'lone pair-lone pair' electron repulsions?
A
$XeF_2$
B
$ClF_3$
C
$IF_5$
D
$SF_4$
Detailed Solution
$XeF_2$ has 2 bond pairs and 3 lone pairs on Xe ($sp^3d$, linear); the three lone pairs are in equatorial positions.
So $XeF_2$ has the maximum (3) lone pair–lone pair repulsions among the given molecules.
So $XeF_2$ has the maximum (3) lone pair–lone pair repulsions among the given molecules.
