Chapter 25, Problem 54QP

Interpretation Introduction

Interpretation:

The movement of electrons is to be shown by the curved arrow in the reaction that takes place with $1,2-\text{dichloroethane}$ by nucleophilic substitution involving a carboxylate site of the enzyme.

Concept introduction:

All the molecules or ions that contain a lone pair of electrons or one pi-bond that hasa tendency of donating electrons to an electrophile are known as nucleophiles.

When an electron rich molecule interacts with an electron deficient molecule having a positive chargethat takes place along with the removal of leavinggroup, it is called a nucleophilic substitution reaction.

Movement of electrons in the reaction mechanism is depicted by curved arrows.
