Passage

The noble gases have closed-shell electronic configuration and are monoatomic gases under normal conditions. The lower boiling points of the lighter noble gases are due to weak dispersion forces between the atoms and the absence of other interatomic interactions.
Direct reaction of xenon with fluorine leads to the formation of a series of compounds with oxidation numbers +2, + 4, + 6 and + 8. XeF4 reacts violently with water to give XeO3. The compounds of xenon exhibit rich stereochemistry and their geometries can be deduced considering the total number of electron pairs in the valence shell.

Test: General Properties & Compounds of Xenon - Question 22

Among XeF2, XeF4, XeF6, XeO3, XeO4, XeO2, XeOF4 the number of compounds that have non-zero dipole moment.


Detailed Solution for Test: General Properties & Compounds of Xenon - Question 22

Correct Answer :- 4

Explanation : XeF4 is square planar and XeF2 is linear in shape. The molecules are symmetrical and so the vector sum of the individual dipole moment is zero.

XeO3 is planar in shape. It has 3 dative bonds(coordinate bonds) in one single plane. Taking into consideration that dipole moment is a vector, the 3 dipole moments of 3 bonds being in same plane and of equal magnitude results in a sum of zero. Therefore the dipole moment of net molecule is 0.
