Interpretation Introduction

Interpretation:

The plausible mechanism of given Bakelite formation 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.

• Phenol formaldehyde resins are artificial polymers obtained by the reaction of phenol or substituted phenol by means of formaldehyde. Second-hand as the basis for Bakelite,
