In the given reaction, movement of electrons should be indicated using curved arrows. Concept introduction: Mechanism of the reaction is the step-by-step description of the process by which reactants are changed into products. Curved arrows used to understand a mechanism. Curved arrows are drawn to show how the electrons move as new covalent bonds are formed existing covalent bonds are broken. Each arrow represents the simultaneous movement of two electrons from a nucleophile towards an electrophile. The tail of the arrow is positioned where the electrons are in the reactant; the tail always starts at a lone pair of electron or at a bond. The head of the arrow points to where these same electrons end up in the product; the arrow always points at an atom or a bond.

Curved arrows used to understand a mechanism.

Curved arrows are drawn to show how the electrons move as new covalent bonds are formed existing covalent bonds are broken.

Each arrow represents the simultaneous movement of two electrons from a nucleophile towards an electrophile.

The tail of the arrow is positioned where the electrons are in the reactant; the tail always starts at a lone pair of electron or at a bond.

The head of the arrow points to where these same electrons end up in the product; the arrow always points at an atom or a bond.
