Chapter 22, Problem 22.14P

(a)

Interpretation Introduction

Interpretation:

Resonance contributor for the cation formed during electrophilic aromatic substitution has to be given for the given ortho-para directing -OH group.

Concept Introduction:

Activating and deactivating groups:

The effect of substituents on the reaction rate of aromatic electrophilic substitution is given by activating or deactivating groups.

Activating groups – ortho/para directing groups.  The rate of reaction is increased by an activating groups (electron donating groups) relative to hydrogen.

Deactivating groups – meta directing groups.  The rate of reaction is decreased by a deactivating groups (electron withdrawing groups) relative to hydrogen.

(b)

Interpretation Introduction

Interpretation:

Resonance contributor for the cation formed during electrophilic aromatic substitution has to be given for the given ortho-para directing -OC(O)CH3 group.

Concept Introduction:

Activating and deactivating groups:

The effect of substituents on the reaction rate of aromatic electrophilic substitution is given by activating or deactivating groups.

Activating groups – ortho/para directing groups.  The rate of reaction is increased by an activating groups (electron donating groups) relative to hydrogen.

Deactivating groups – meta directing groups.  The rate of reaction is decreased by a deactivating groups (electron withdrawing groups) relative to hydrogen.

(c)

Interpretation Introduction

Interpretation:

Resonance contributor for the cation formed during electrophilic aromatic substitution has to be given for the given ortho-para directing -N(CH3)2 group.

Concept Introduction:

Activating and deactivating groups:

The effect of substituents on the reaction rate of aromatic electrophilic substitution is given by activating or deactivating groups.

Activating groups – ortho/para directing groups.  The rate of reaction is increased by an activating groups (electron donating groups) relative to hydrogen.

(d)

Interpretation Introduction

Interpretation:

Resonance contributor for the cation formed during electrophilic aromatic substitution has to be given for the given ortho-para directing -NHC(O)CH3 group.

Concept Introduction:

Activating and deactivating groups:

The effect of substituents on the reaction rate of aromatic electrophilic substitution is given by activating or deactivating groups.

Activating groups – ortho/para directing groups.  The rate of reaction is increased by an activating groups (electron donating groups) relative to hydrogen.

(a) Tsomane and Nyiko were given a task of synthesising methylenecyclohexane 2. After a brief discussion with each other, Tsomane proposed Method A to synthesise 2 from cyclohexanone 1 while Nyiko proposed Method B that started from hydroxymethylcyclohexane 3. Each student believed that their proposed method is better than the other.
