Question: What is the bond order of a molecule with 10 electrons in a molecular orbital diagram?

Options:

  1. 0
  2. 1
  3. 2
  4. 3

Correct Answer: 2

Solution: 

Bond order = (number of bonding electrons - number of antibonding electrons) / 2. For 10 electrons, if all are bonding, bond order = 10/2 = 5. If 2 are antibonding, bond order = (10-2)/2 = 4. The most stable configuration gives a bond order of 2.

Questions & Step-by-Step Solutions

What is the bond order of a molecule with 10 electrons in a molecular orbital diagram?
  • Step 1: Understand that bond order is a way to measure the stability of a bond in a molecule.
  • Step 2: Know the formula for bond order: Bond order = (number of bonding electrons - number of antibonding electrons) / 2.
  • Step 3: Identify the total number of electrons in the molecule, which is given as 10.
  • Step 4: Determine how many of those 10 electrons are in bonding orbitals and how many are in antibonding orbitals.
  • Step 5: If all 10 electrons are bonding, calculate bond order: Bond order = 10 / 2 = 5.
  • Step 6: If 2 electrons are in antibonding orbitals, calculate bond order: Bond order = (10 - 2) / 2 = 4.
  • Step 7: Consider the most stable configuration, which typically gives a bond order of 2.
  • Bond Order Calculation – Bond order is calculated using the formula (number of bonding electrons - number of antibonding electrons) / 2, which indicates the stability and strength of a bond.
  • Molecular Orbital Theory – Understanding how electrons fill molecular orbitals and the distinction between bonding and antibonding orbitals is crucial for determining bond order.
