← ScienceWhich consequence results when overlap destabilizes during sigma bond formation?
A)Increased molecular orbital energy✓
B)Greater vibrational mode stability
C)Electron density stays unaffected
D)Reduced interatomic nuclear repulsion
💡 Explanation
Increased molecular orbital energy emerges because constructive interference, part of Linear Combination of Atomic Orbitals, weakens due to lessened sigma-bond overlap; therefore, energy elevates because antibonding interactions dominate rather than stabilizing effects of bonding orbitals.
