Xenon can be the central atom of a molecule by expanding beyond an octet of electrons. Draw Lews structures for the following xenon compounds. Show all lone pairs.

Could please draw it for me? Thank you..

Answer 1

Concepts and reason

Xenon is a zero-group element.

Ground state electronic configuration of the element is $\left[ {{\rm{Kr}}} \right]{\rm{ }}4{d^{10}}5{s^2}5{p^6}$ . All the orbitals are filled.

Write the excited state electronic configuration as shown below.

$\left[ {{\rm{Kr}}} \right]{\rm{ }}4{d^{10}}5{s^2}5{p^5}5{d^1}$

In the excited xenon has two unpaired electrons, these are involved in the formation of bond with the two fluorine atoms.

Draw the Lewis structures for the molecules ${\rm{Xe}}{{\rm{F}}_{\rm{2}}}$ and ${\rm{Xe}}{{\rm{F}}_{\rm{2}}}{\rm{O}}$ based on the valences of the elements present in the molecules and complete their octet.

Fundamentals

Lewis structure is a diagram that show bonding between atoms in a molecule and shows lone pair of electrons present on the atoms.

Atomic number of xenon atom is 54.

In the molecule, ${\rm{Xe}}{{\rm{F}}_{\rm{2}}}$ , the central atom xenon is surrounded with two fluorine atoms.

Lewis structure of the molecule is as follows:

In the molecule, ${\rm{Xe}}{{\rm{F}}_{\rm{2}}}{\rm{O}}$ , the central atom xenon is surrounded with two fluorine atoms and one oxygen atom.

Lewis structure of the molecule is as follows:

Ans:

Lewis structure of the molecule ${\rm{Xe}}{{\rm{F}}_{\rm{2}}}$ is as follows:
