Bond Energy Calculation

Bond energy refers to the amount of energy required to break the bond between two atoms. The higher the bond energy, the stronger the bond between the two atoms. The bond energy can be calculated using the formula:

Bond energy = (Energy required to break the bond) / (Number of bonds broken)

Factors Affecting Bond Energy

The bond energy is affected by various factors such as:

1. Atomic size: The bond energy decreases with an increase in the atomic size.

2. Electronegativity: The bond energy increases with an increase in the electronegativity of the atoms.

3. Bond length: The bond energy decreases with an increase in the bond length.

Maximum Bond Energy

The bond energy of the diatomic molecules F2, N2, and O2 can be calculated using the formula mentioned above. The bond energy of these molecules is as follows:

- F2: 157 kcal/mol
- N2: 226 kcal/mol
- O2: 142 kcal/mol

From the above values, it can be concluded that the maximum bond energy is in N2. Therefore, the correct answer is option (b) N2.

Conclusion

The bond energy of a molecule depends on various factors such as atomic size, electronegativity, and bond length. The bond energy of F2, N2, and O2 can be calculated using the formula mentioned above, and it is found that the maximum bond energy is in N2.
