VSEPR theory does bot state :

Answer»

the order of repulaion between different pair of elctrons is `lp - lp GT lp - bp gt bp = bp` (lp = lone pair ELECTRONS, bp = bond pair electrons)
as the number of lone pair of electrons on central atom increases, the deviation in BA form normal BA (Bond-Angle) ALSO increases.
the number of lone pairs on O in `H_(2)O` is 1 while on N in `NH_(3)` is 2.
the structures of xenon-fluorides and xenon-oxyfluorides could be explained on the basis of VSEPR theory.
