Electrophilic aromatic substitution
When phenol and formaldehyde react to form Bakelite, the initial reaction between them is an example of electrophilic aromatic substitution. This reaction involves the substitution of a hydrogen atom on an aromatic ring with an electrophile.
Phenol and formaldehyde reaction
- Phenol and formaldehyde react to form a molecule called hydroxymethyl phenol.
- This reaction is initiated by the attack of the hydroxyl group of phenol on the electrophilic carbon of formaldehyde.
- The resulting intermediate undergoes further reactions to form the final Bakelite polymer.
Electrophilic aromatic substitution mechanism
- In electrophilic aromatic substitution, the aromatic ring acts as a nucleophile attacking an electrophilic species.
- The attack leads to the formation of a sigma complex intermediate, which is stabilized by resonance.
- Subsequent steps involve the removal of a proton to regenerate the aromatic character of the ring.
Importance of electrophilic aromatic substitution in Bakelite formation
- The electrophilic aromatic substitution reaction is crucial in the formation of Bakelite as it allows for the incorporation of formaldehyde into the aromatic ring of phenol.
- This reaction pathway leads to the formation of a three-dimensional network polymer known as Bakelite, which possesses valuable properties such as heat resistance and electrical insulation.
