Question

draw the structure of O2 molecule and N2 molecule based on vbt

Answer 1

Atomic no. Of oxygen is 8
Atomic no. Of nitrogen is 7
So...

Answer 2

Structure of O2 molecule and N2 molecule based on vbt is O=O and N≡N

Explanation:

For oxygen molecule -

• The electronic configuration of O is $1s2 2s2 2px2 spy1 spz1.$

• if the py orbital of one oxygen atom overlaps the py orbital of the other oxygen atom along with the internuclear axis a sigma $py-py$ bond is formed.

• If the py orbital of one of the oxygen atoms overlaps laterally with the py of other oxygen atoms along the internuclear axis a bond will be formed.

• Pz orbital of oxygen atom will overlap laterally perpendicular to the internuclear axis giving a π pz – pz bond.
• Thus oxygen will have a double bond between the oxygen atoms

For nitrogen molecule -

• The electronic configuration of N is $1s 2 2s 2 2p 3 .$

• if the py orbital of one nitrogen atom overlaps the py orbital of the other nitrogen atom along with the internuclear axis a sigma $py-py$ bond is formed.

• If the py orbital of one of the nitrogen atoms overlaps laterally with the py of other nitrogen atoms along the internuclear axis a bond will be formed.
• Pz orbital of nitrogen atom will overlap laterally perpendicular to the internuclear axis giving a π pz – pz bond.
• There are six electrons shared between the two nitrogen atoms forming a triple bond
• Thus nitrogen will have a triple  bond between the nitrogen atoms
