MHT CET Chemistry question

Select the INCORRECT statement about inert gases

(A)The ionization enthalpy of each inert gas is the highest in its period
(B)Inert gas have large negative values of electron gain enthalpyCorrect
(C)The atomic radii of inert gases are larger than those of halogens
(D)All the inert gases are monoatomic in nature

Answer: (B)

Solution

Inert gases have the highest ionisation enthalpy in each period, are monoatomic and have larger (van der Waals) radii than halogens, so (a), (c) and (d)
