The potential energy (y) curve for H2 formation as a function of internuclear distance (x) of the H atoms is shown below.

 

The bond energy of H2 is

Option: 1

\frac{\left ( c-a \right )}{2}
 


Option: 2

\frac{\left ( b-a \right )}{2}


Option: 3

\left ( c-a \right )

 


Option: 4

\left ( b-a \right )

The minima in the above curve represent bond formation.

Thus, the bond energy is (b-a), which is the amount of energy released when two-mole hydrogen atoms are forming one mole of hydrogen molecule. 

Hence, the correct answer is option 4.
