(a)

Answer to Problem 11.37P
The order of decreasing bond energy of
Explanation of Solution
The molecular orbital diagram of
The formula to calculate the bond order is as follows:
Substitute 7 for the number of electrons in bonding orbitals and 4 for the number of electrons in antibonding orbitals in equation(1).
The molecular orbital diagram of
Substitute 6 for the number of electrons in bonding orbitals and 4 for the number of electrons in antibonding orbitals in equation(1).
The molecular orbital diagram of
Substitute 5 for the number of electrons in bonding orbitals and 4 for the number of electrons in antibonding orbitals in equation(1).
Bond energy is directly proportional to the bond order. The highest bond order of
So the order of decreasing bond energy is
The order of decreasing bond energy of

Interpretation:
The order of decreasing bond length of
Concept introduction:
A molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

The molecular orbital diagram of
Substitute 6 for the number of electrons in bonding orbitals and 4 for the number of electrons in antibonding orbitals in equation(1).
The molecular orbital diagram of
Substitute 5 for the number of electrons in bonding orbitals and 4 for the number of electrons in antibonding orbitals in equation(1).
Bond length decreases with the increase in bond energy. The highest bond order of
So the order of the decreasing bond length is
The order of the decreasing bond length is
