Lewis structure, hybridization, and bond angle of
Concept Introduction:
Hybridization is calculated by the hybrid orbitals and to calculate hybrid orbitals we need to know the steric number that is given by,
The table that relates the steric number with hybridization is as follows:
The table that relates steric number with geometry and bond angles is as follows:

Hybridization of
Explanation of Solution
The molecule
The symbol for xenon is
The symbol for oxygen is
Thus total valence electrons are sum of the valence electrons for each atom in
The skeleton structure
To complete the octet of xenon it forms a double bond with three oxygen atom.
Hence, 14 electrons are allocated as 2 lone pairs on each oxygen atoms and 1 lone pair on xenon atom to complete their octet. The Lewis structure is as follows:
In the structure of
Substitute 3 for number of atoms bonded with central atom and 1 for lone pair on central atom in equation (1) to calculate steric number.
Since, the steric number of the molecule
The molecule
The symbol for xenon is
The symbol for oxygen is
Thus total valence electrons are sum of the valence electrons for each atom in
The skeleton structure
To complete the octet of xenon it forms a double bond with four oxygen atoms.
Hence, 16 electrons are allocated as 2 lone pairs on each oxygen atoms to complete its octet. The Lewis structure is as follows:
In the structure of
Substitute 4 for atoms bonded with central atom and 0 lone pair on central atom in equation (1) to calculate steric number.
Since, the steric number of the molecule
The molecule
The symbol for xenon is
The symbol for oxygen is
Four negative charges on molecule are added up in the total valence count.
Thus total valence electrons are sum of the valence electrons for each atom in
The skeleton structure
To complete the octet of xenon it forms a double bond with two oxygen atoms.
Hence, 32 electrons are allocated as 2 lone pairs on two doubly bonded oxygen atoms and 3 lone pairs on remaining oxygen atoms to complete their octet. The Lewis structure is as follows:
In the structure of
Substitute 6 for number of atoms bonded with central atom and 0 for lone pair on central atom in equation (1) to calculate steric number.
Since the steric number of the molecule
Bond order is the number of electrons involved between the two atoms in a molecule. Bond order is inversely related to bond length.
