Chapter 27, Problem 5E

Interpretation Introduction

(a)

Interpretation:

The organic reaction between ethene and ${\text{Br}}_{\text{2}}$ in carbon tetrachlroide sholud be written and classified.

Concept introduction:

Addition reaction is defined as the reaction in which two or more molecules combine to form a single and large molecule. It occurs only in molecules that contain multiple bonds (double or triple bonds). It can be an electrophilic, nucleophilic reaction or free radical addition reaction.

Interpretation Introduction

(b)

Interpretation:

The organic reaction between iodoethane and $\text{KOH}$ should be written and classified.

Concept introduction:

The elimination reaction is a type of organic reaction that includes removal of substituent from reactants. It occurs in the compounds that are saturated and contain only single bonds. It takes place by two mechanisms- $\text{E1}$ and $\text{E2}$ mechanisms.

Interpretation Introduction

(c)

Interpretation:

The organic reaction between chloromethane and sodium hydroxide should be written and classified.

Concept introduction:

Substitution reactions are the chemical reactions in which an atom, ion or group in one molecule is replaced by the other. These are also known as the single displacement or single substitution reactions.
