Chapter 6, Problem 26P

Interpretation Introduction

Interpretation:

The reaction which gives the best yield of styrene is to be chosen.

Concept introduction:

Substitution reaction: A reaction in which one of the hydrogens of a hydrocarbon or a functional group is substituted by any other functional group is called substitution reaction. Substitution reactions the hybridization of the central atom remains same that is sp³.

Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction. The hybridization of the atoms thus changes from sp³ to sp².

Nucleophilic substitution reaction: A reaction in which one of the hydrogens of a hydrocarbon or a functional group is substituted by any nucleophile is called substitution reaction.

A nucleophile is a molecule or atom with most negative charge.

There are two types of nucleophilic substitution reactions: ${\text{S}}_{\text{N}}1$ is a unimolecular reaction and ${\text{S}}_{\text{N}}\text{2}$ is a bimolecular reaction.
