In each of the following question, a statement of Assertion (A) is given followed by a corresponding statement of Reason (R). Choose the correct answer as:
Assertion (A): Xenon formed fluorides.
Reason (R): Because 5d orbitals are available for valence shell expansion.
Answer & explanation
Correct answer: option 1
Xenon belongs to noble gases which are considered to be very unreactive. In xenon atom, the ionisation potential of Xe to lose one electron was found to be nearly equivalent that of
O2 →O2+ + e-
Also, due to the presence of empty 5d-orbitals, electrons can be excited and higher valency of xenon can be produced. e.g., XeF2, XeF4, XeF6 etc.
