Concept:

Nucleophilic substitution reactions-

Substitution reactions are the types of reactions where a nucleophile is the attacking reagents.

• There are three types of substitution reactions depending on the nature of the substrate.
  • Nucleophilic substitution at saturated carbon. 
  • Nucleophilic acyl substitution
  • Nucleophilic aromatic substitution.
• Nucleophilic substitution reaction is mainly of two types. These are SN1 or Unimolecular nucleophilic substitution and SN2 or bimolecular nucleophilic substitution
• SN1 or Unimolecular nucleophilic substitution:
  • Depends upon the concentration of the substrate.
  • Is independent of the concentration of the nucleophile.
  • Follows first-order kinetics.
• SN2 or bimolecular nucleophilic substitution:
  • The rate depends on the concentration of both the reactant and the substrate.
  • It follows second-order kinetics.

Given below are the examples of SN2 and SN1 nucleophilic substitution reactions:

Explanation:-

• The reaction pathway is shown below:

• In the above reaction, it is shown that in the first step of the reaction the nucleophile PhSO₂^- undergoes an S_N2 type nucleophilic substitution reaction in a polar protic solvent (MeOH) to give the final product.

Conclusion:-

• Hence, the major product formed in the following reaction is
