Interpretation Introduction

Interpretation:The reaction schemes with proper usage of curved arrows in below reaction should be indicated and corrected for the cases that are inappropriate.

  

Concept introduction:The fundamental electrostatics suggests that electrons have more affinity for electron-deficient sites in an organic compound. or positive charge. The curved arrow is appropriate mechanism to depict electron movement that occurs from electron rich species to electron deficient species.

Bimolecular substitution or ${\text{S}}_{\text{N}}2$ proceeds via single-step mechanism. Thus it is well known as concerted mechanism. Nucleophile approaches carbon while the leaving group still departs from the rear side (opposite to leaving group). The transition state only illustrates the geometric orientation of the substrates and reagents as they pass through the maxima in the single-step mechanism.

A general ${\text{S}}_{\text{N}}2$ reaction mechanistic pathway is illustrated below:
