(a)

Interpretation Introduction

Interpretation:

Product and optical activity given following reaction has to be predicted.

Concept Introduction:

• Electrophiles are electron deficient species. In Electrophilic substitution reaction a group or atom in a compound is replaced by electrophile. This kind of reaction occurs predominantly in aromatic compounds. Electrophilic substitution reactions of aromatic compounds are known as aromatic electrophilic substitution reactions.

• Benzene is an electron rich Aromatic compound. It undergoes aromatic electrophilic substitution reaction. 

• The delocalized nature of pi electrons in benzene attributes a special property to benzene called resonance.
• Enantiomers are chiral molecules to be mirror imagery of one another. In addition, the molecules are non-super imposable on one a new. This resource that the molecules cannot be placed on tops of one a further and give the similar molecule.
• Diastereomers are stereoisomer’s that are not mirror images of one another and are non-super imposable on one another.

• Friedel-Crafts Alkylation: This Lewis acid-catalyzed electrophilic aromatic replacement allows the synthesis of alkylated products by means of the reaction of arenes through alkyl halides or alkenes.
