Interpretation Introduction

(a)

Interpretation: The change that occurs to the rate of an ${\text{S}}_{\text{N}}\text{2}$ reaction when $\left[\text{RX}\right]$ is tripled and $\left[{\text{Nu}}^{-}\right]$ stays the same is to be predicted.

Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron rich chemical species that contains negative charge or lone pair of electrons are known as a nucleophile. In a nucleophilic substitution reaction, nucleophile takes the position of leaving group by attacking the electron deficient carbon atom.

Interpretation Introduction

(b)

Interpretation: The change that occurs to the rate of an ${\text{S}}_{\text{N}}\text{2}$ reaction when both $\left[\text{RX}\right]$ and $\left[{\text{Nu}}^{-}\right]$ are tripled is to be predicted.

Interpretation Introduction

(c)

Interpretation: The change that occurs to the rate of an ${\text{S}}_{\text{N}}\text{2}$ reaction when $\left[\text{RX}\right]$ is halved and $\left[{\text{Nu}}^{-}\right]$ stays the same is to be predicted.

Interpretation Introduction

(d)

Interpretation: The change that occurs to the rate of an ${\text{S}}_{\text{N}}\text{2}$ reaction when $\left[\text{RX}\right]$ is halved and $\left[{\text{Nu}}^{-}\right]$ is doubled is to be predicted.
