प्रश्न
Which one of the following does not exist?
(i) XeOF4
(ii) NeF2
(iii) XeF2
(iv) XeF6
उत्तर १
NeF2 does not exist.
उत्तर २
NeF2 does not exist. This is because the sum of first and second ionization enthalpies of Ne are much higher than those of Xe. Consequently, F2 can oxidise Xe to Xe2+ but cannot oxidise Ne to Ne2+.
