What is MOlecular Orbital Theory?
Explain the molecule of nitroge with the help of this theory and give the bond order of nitrogen molecule......
According to this theory,
1. As the electron of an atom are present in various atomic orbitals, electrons of a molecular are present in various molecular orbitals.
2. Molecular orbitals are formed by the combination of atomic orbitals of comparable energy and proportional symmetry.
3. While an electron in atomic orbital is influenced by one nucleus, in MOT, it is influenced by two or more nuclei depending upon the number of atoms in nuclei.
4. The number of molecular orbitals formed is equal to the number of combining atomic atoms.
5. When two atomic orbital combine, two molecular orbitals are formed. One is known as bonding molecular orbital and other is called anti bonding molecular orbital.
Bond order = No. of electron in bonding MOs - No. of electron in antibonding orbital/2.
MO Configuration :
N2(14e-) =σ1s2σ*1s2σ2s2σ*2s2(π2px2=π2py2)σ2pz 2 thus Bond order = 10-4/2 =6/2= 3
