question_answer 58)

    In the preparation of compounds of Xe, Bartlett had taken   Pt as a base compound. This is because (a) both  and Xe have same size. (b) both  and Xe have same electron gain enthalpy. (c) both and Xe have almost same ionisation enthalpy. (d) both Xe and  are gases.

Answer:

                    (c) Bertlett had taken  Pt  as a base compound because O2 and Xe both have almost same ionisation enthalpy The ionisation enthalpies of noble gases are the highest in their respective periods due to their stable electronic configurations.
