Question

with the help of MOT write the energy level diagram of hydrogen molecule.what is it's bond order and predict magnetic property​

Answer 1

Bond order of Hydrogen is one and it is diamagnetic substance

Explanation:

According to MOT hydrogen molecule is formed by the combination of two hydrogen atoms.

• Total no. of electrons in hydrogen molecule = 1+1 = 2

• Electronic configuration is $\sigma 1s^2\sigma^* 1s^0$    
• Molecular Orbital Energy Level Diagram can be represented as below

• $Bond order =\frac{N_b-N_a}{2}$      

                  $=\frac{2-0}{2}=1$

• And there are no unpaired electrons in molecular orbitals. Hence it is              diamagnetic molecule.

Answer 2

Explanation:

According to MOT hydrogen molecule is formed by the combination of two hydrogen atoms.

Total no. of electrons in hydrogen molecule = 1+1 = 2

Electronic configuration is \sigma 1s^2\sigma^* 1s^0σ1s2σ∗1s0    

Molecular Orbital Energy Level Diagram can be represented as below

Bond order =\frac{N_b-N_a}{2}Bondorder=2Nb−Na      

                  =\frac{2-0}{2}=1=22−0=1

And there are no unpaired electrons in molecular orbitals. Hence it is              diamagnetic molecule.
