E)complete retention at the center undergoing substitution.

Question

Quizplus · Accepted Answer

Substitutions usually proceed with slightly more inversion than retention at the center undergoing substitution. This is known as the Walden inversion, where the stereochemistry of the substrate is inverted during the substitution reaction. However, the degree of inversion and retention can depend on several factors such as the nature of the substrate, the reaction conditions, and the mechanism of the reaction. So, reaction outcomes can vary, but generally, the Walden inversion is observed.
