Why has it been difficult to study the chemistry of radon?
1 It is very rarely available
2 It is radioactive and has a very short half life
3 It is a noble gas
4 It doesn't react at all
Explanation:
Radon is radioactive with very short halflife which makes the study of chemistry of radon difficult.

Which among the following noble gases reacts with fluorine to give crystalline fluorides?
1 \(\mathrm{Ne}\)
2 \(\mathrm{He}\)
3 \(\mathrm{Xe}\)
4 \(\mathrm{Ar}\)
Explanation:
Xenon forms fluorides like \(\mathrm{XeF}_{2}, \mathrm{XeF}_{4}\), \(\mathrm{XeF}_{6}\).

In the preparation of compounds of \(\mathrm{Xe}\), Bartlett had taken \({\rm{O}}_{\rm{2}}^{\rm{ + }}{\rm{Pt}}\,{\rm{F}}_{\rm{6}}^{\rm{ - }}\) as a base compound. This is because
1 Both \(\mathrm{O}_{2}\) and \({\rm{Xe}}\) have same size
2 Both \(\mathrm{O}_{2}\) and \({\rm{Xe}}\) have same electron gain enthalpy
3 Both \(\mathrm{O}_{2}\) and \({\rm{Xe}}\) have almost same ionisation enthalpy
4 Both \({\rm{Xe}}\,\,{\rm{and}}\,\,{{\rm{O}}_{\rm{2}}}\) are gases

Assertion : Xenon forms fluorides. Reason : Because 5d- orbitals are available for valence shell expansion.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Xenon forms fluorides primarily because only fluorine and oxygen are electronegative enough to excite electrons of Xenon into its vacant 5d-orbitals and allow bonding. So option (1) is correct.
