Interpretation Introduction

Interpretation:

The reactions which are faster in water, ethanol and the one which is solvent invariant are to be stated.

Concept introduction:

Nucleophilic substitution reaction is the reaction in which a nucleophile attack on a positively charged atom and replaces leaving group. It is of two types ${\text{S}}_{\text{N}}1$ and ${\text{S}}_{\text{N}}\text{2}$. In ${\text{S}}_{\text{N}}1$, intermediate carbocation is formed and it is a unimolecular reaction. In ${\text{S}}_{\text{N}}\text{2}$, the transition state is formed and it is a biomolecular reaction.
