← ScienceWhich mechanism stabilizes bonding in the H2+ ion?
A)Quantum tunneling of the electron✓
B)Resonance stabilization between protons
C)Electron spin-pairing interactions
D)Enhanced nuclear shielding effects
💡 Explanation
Quantum tunneling allows the electron's wave function to penetrate both proton potentials, lowering energy because the electron effectively occupies more space. This increased delocalization stabilizes the bond rather than alternatives that rely solely on localized interactions.
