Which risk grows when overlapping atomic orbitals are spatially constrained?

A)Steric hindrance weakens bonding.
B)Increased London-force dispersion.
C)Electron affinity becomes negative.
D)Diamagnetism becomes strongly paramagnetic.

💡 Explanation

Steric hindrance destabilizes molecules because van der Waals repulsion overwhelms bonding when atoms are forced too close, affecting orbital overlap. Therefore, steric hindrance increases rather than enhanced molecule stabilty; this occurs under constraint rather than weaker attraction.
