For the product with the given molecular formula, the structural formula has to be proposed. 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.

Interpretation Introduction

Interpretation:

For the product with the given molecular formula, the structural formula has to be proposed.

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.
