Chapter 17, Problem 17.10YT

Interpretation Introduction

Interpretation:

Triphenylphosphine being a very good nucleophile is to be verified by looking up its relative nucleophilicity and that of ${\text{Br}}^{\text{-}}$.

Concept introduction:

Nucleophile is a chemical species with negative charge and has a lone pair, which it can donate to form a chemical bond. Nucleophilicity refers to a nucleophile character of nucleophile. Bromine ion ${\text{(Br}}^{\text{-}}\text{)}$ is a very good nucleophile.
