How is bond order (b.o.) defined?

Options

  1. AIt is the sum of electrons in bonding and antibonding orbitals.
  2. BIt is the difference between the numbers of electrons in bonding and antibonding orbitals.
  3. CIt is the ratio of electrons in bonding to antibonding orbitals.
  4. DIt is the average energy of bonding and antibonding orbitals.

Correct answer

B. It is the difference between the numbers of electrons in bonding and antibonding orbitals.

Step-by-step solution

The bond order is half the difference between the number of electrons in bonding (N b ) and antibonding (N a ) orbitals.
