Treating phenol with formaldehyde in the presence of dilute base forms:
Correct answer: C. Condensation polymerization
- A. Oxidation
- B. Elimination
- C. Condensation polymerization
- D. Additional polymerization
Explanation
Treating phenol with formaldehyde in the presence of a dilute base results in the formation of Bakelite through a condensation polymerization process. Treating phenol with formaldehyde in the presence of a dilute base results in the formation of Bakelite through a condensation polymerization process.Bakelite is a type of thermosetting plastic that was one of the first synthetic plastics to be produced on an industrial scale. The reaction involved in its formation is known as the Bakelite or phenol-formaldehyde resin synthesis.The reaction proceeds through the condensation polymerization of phenol and formaldehyde molecules. Typically, paraformaldehyde (a polymerized form of formaldehyde) is used as a source of formaldehyde.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
