Question

Consider the four xenon compounds xef2, xef4, xef6, xeo3. The pair of compound expected to have non-zero dipole moment

Answer 1

istry, and the theory of binding in the xenon compounds has been .... Small amounts of XeF2 have also been prepared with- ... XeF4 ( or fluorine) with excess xenon at high pressure.

Answer 2

Answer:

XeF4 and XeF6.

Explanation:

XeF4 is pyramidal with one lone pair and XeF6 is distorted octahedral having one lone pair.

XeF2 has trigonal bipyramidal geometry having two F at axial position while three lone pairs on equitorial position making it linear hence zero dipole moment.

Dipole moments occur when there is a separation of charge. They can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. The larger the difference in electronegativity, the larger the dipole moment.
