Question

Draw the product you expect from the reaction of (s)-3-iodohexane with ch3co2-. be sure to show stereochemistry.

Answer 1

This will give substituted product which will be by SN2 mechanism

so here we will get product with inverted geometry

In SN2 mechanism the nucleophile attacks from back side and we always get product with inverted geometry

This is known as Walden inversion.
