Which one of the following does not exist?

(i) XeOF4 (ii) NeF2 (iii) XeF2 (iv) XeF6


NeF2does not exist as it would require d orbital for bonding which Ne does not have as it belongs to period 2 and moreover a lot of energy would be used to excite the electrons to a higher energy level as the valence electrons are very close to the nucleus thus they experience strong electrostatic attraction.
