Bond Order Calculator

Molecular Orbital Theory

Calculate bond order to determine bond strength, stability, and molecular properties using molecular orbital theory.

Calculator

Number of electrons in bonding molecular orbitals

Number of electrons in antibonding molecular orbitals

Formula:
Bond Order = (Nb - Na) / 2
Higher bond order = stronger, shorter bond

About Bond Order

Bond order indicates the number of chemical bonds between atoms and determines bond strength and stability.

Key Relationships:
  • Higher bond order = stronger bond
  • Higher bond order = shorter bond
  • Bond order 0 = no bond
  • Fractional = resonance

Features

Common Molecules

Hâ‚‚: Bond Order = 1 (Single)
Oâ‚‚: Bond Order = 2 (Double)
Nâ‚‚: Bond Order = 3 (Triple)
Fâ‚‚: Bond Order = 1 (Single)
Heâ‚‚: Bond Order = 0 (No bond)

Molecular Orbitals

Bonding (σ, π): Lower energy, stabilize molecule

Antibonding (σ*, π*): Higher energy, destabilize molecule

Non-bonding: No effect on bond order
