Chapter 9, Problem 9.16P

Interpretation Introduction

Interpretation:

The nucleophile among $\text{:N}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\right)}_{\text{3}}$ and $\text{:P}{\left({\text{C}}_{\text{2}}{\text{H}}_{\text{5}}\right)}_{\text{3}}$ which reacts most rapidly with methyl iodide in the ethanol as solvent is to be stated and explained. The products formed in corresponding cases are to be stated.

Concept introduction:

The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile. These reactions depend upon the nucleophilicity and concentration of the incoming nucleophile.

The ${\text{S}}_{\text{N}}\text{2}$ reaction is a nucleophilic substitution bimolecular reaction in which the addition of incoming nucleophile and removal of existing nucleophile takes place simultaneously. The rate of reaction depends upon both the substrate and reactant in the rate law equation.
