Predict the correct order among the following.
A
lone pair-lone pair > bond pair-bond pair > lone pair-bond pair
B
bond pair-bond pair > lone pair-bond pair > lone pair-lone pair
C
lone pair-bond pair > bond pair-bond pair > lone pair-lone pair
D
lone pair-lone pair > lone pair-bond pair > bond pair-bond pair
Explanation
lp–lp > lp–bp > bp–bp.
Detailed Solution
According to VSEPR theory, lone pairs of electrons are more diffused than bond pairs. So the order of repulsion is: lone pair–lone pair > lone pair–bond pair > bond pair–bond pair.
