Which consequence results when steric hindrance restricts orbital hybridization?

A)Reduced reaction rate constant
B)Increased solvation shell formation
C)Enhanced fluorescence quantum yield
D)Elevated vibrational mode frequency

💡 Explanation

Steric hindrance blocks the optimal alignment of reactant molecules for ideal sp3 orbital overlap, leading to a lower energy transition state by destabilizing the intermediate, and therefore decreasing reaction rate constant, rather than other photophysical or solvation effects.
