CONCEPT:

Bakelite Preparation

• Bakelite is a type of plastic, specifically a phenolic resin, that is created by the reaction of phenol with formaldehyde.
• The reaction involves the formation of a complex network polymer through a condensation reaction.
• This polymer is known for its high resistance to heat and chemicals, making it useful in electrical insulators and various other applications.

EXPLANATION:

• In the given reaction for the preparation of Bakelite:

  Phenol + Formaldehyde → Bakelite

  • Phenol acts as the primary reactant, providing the aromatic ring structure.
  • Formaldehyde acts as the linking agent, forming methylene bridges between the phenol units.
• 
• Among these options, the correct pair of reactants for the formation of Bakelite is:
  • Option 3: Phenol and formaldehyde

Therefore, Bakelite is prepared by the reaction between phenol and formaldehyde.
