Bond Order Formula:
From: | To: |
Bond order is a measurement of the number of electrons involved in bonds between two atoms. It provides insight into bond strength and stability - higher bond orders indicate stronger, more stable bonds.
The calculator uses the bond order formula:
Where:
Explanation: The formula calculates the net number of bonding electrons (bonding minus antibonding) divided by 2 to get bond order.
Details: Bond order helps predict bond length (inverse relationship) and bond energy (direct relationship). It's fundamental in molecular orbital theory and understanding chemical reactivity.
Tips: Enter the number of bonding and antibonding electrons (must be non-negative integers). The calculator will compute the bond order as a dimensionless number.
Q1: What does a bond order of 0 mean?
A: A bond order of 0 indicates no bond exists between the atoms (number of bonding and antibonding electrons are equal).
Q2: What are typical bond order values?
A: Common values are 1 (single bond), 2 (double bond), and 3 (triple bond). Fractional values occur in resonance structures.
Q3: Can bond order be negative?
A: No, bond order cannot be negative. If calculation gives a negative value, it means there are more antibonding than bonding electrons, indicating no stable bond.
Q4: How is bond order related to bond length?
A: Higher bond order correlates with shorter bond length. For example, a triple bond (BO=3) is shorter than a double bond (BO=2).
Q5: What's the difference between bond order and valence bond theory?
A: Bond order comes from molecular orbital theory, considering all electrons in the molecule. Valence bond theory focuses on electron pairs between specific atoms.
