उत्तर
(i) Only type of interactions between particles of noble gases are due to weak dispersion forces.
(ii) Ionisation enthalpy of molecular oxygen is very close to that of xenon.
Explanation:
Weak dispersion forces are present between particles of noble gases. The Ionization enthalpy of molecular oxygen is very close to that of xenon.
