Question

Draw curved arrows to show the flow of electrons responsible for the conversion of the reactants to products

Short answer

The reaction proceed through E² mechanism and the curved arrow representation of the mechanism is given below.

Step-by-step solution

Mechanism pathway

The formation of the product happens through E² mechanism which is an elimination pathway. In this mechanism, the transition state is 5 membered, the bond breaking and making process happens simultaneously, which means it only needs one step for conversion of the reactant to product.
