Chapter 15, Problem 15.42P

(a)

Interpretation Introduction

Interpretation:

The equation for an addition reaction between 3-hexene and ${\text{H}}_{\text{2}}\text{O}$ (${\text{H}}^{\text{+}}$ is a catalyst) has to be written.

Concept Introduction:

The addition reaction is a type of organic reaction which can be identified by the number of bonds to carbon in reactants and products.

Addition reaction:

When an unsaturated reactant becomes a saturated product, the reaction is said to be addition reaction.

(b)

Interpretation Introduction

Interpretation:

The equation for an elimination reaction between 2-bromopropane and hot potassium ethoxide, ${\text{CH}}_{\text{3}}{\text{-CH}}_{\text{2}}\text{-OK}$ ($\text{KBr}$ and ethanol are also products) has to be written.

Concept Introduction:

The elimination reaction is a type of organic reaction which can be identified by the number of bonds to carbon in reactants and products.

Elimination reaction:

When a saturated reactant becomes an unsaturated product, the reaction is said to be elimination reaction.

(c)

Interpretation Introduction

Interpretation:

The equation for a light induced substitution reaction between ${\text{Cl}}_{\text{2}}$ and ethane to form 1,1-dichloroethane has to be written.

Concept Introduction:

The substitution reaction is a type of organic reaction which can be identified by the number of bonds to carbon in reactants and products.

Substitution reaction:

When a group or an atom in the reactant is substituted by a group or an atom from the other reactant, the reaction is said to be substitution reaction.  In substitution reaction, the substitution occurs on the carbon from which a group or an atom is removed.
