Bakelite is a type of thermosetting plastic which is prepared by the reaction between Phenol and Formaldehyde.
Explanation:
- Bakelite was the first synthetic plastic which was invented by Belgian chemist Leo Baekeland in 1907.
- It is formed by the reaction between Phenol (C6H5OH) and Formaldehyde (HCHO) in the presence of a catalyst like hydrochloric acid or zinc chloride.
- This reaction is called Condensation Polymerization or Step-Growth Polymerization as it involves the combination of smaller molecules to form a larger molecule with the elimination of a small molecule like water or methanol.
- The reaction proceeds as follows:
Phenol + Formaldehyde → Bakelite + Water
- The Bakelite formed is a hard and durable plastic which can withstand high temperatures, pressures, and electrical insulations.
- It is widely used for making electrical switches, handles, knobs, and other household items.
Conclusion:
Hence, the correct option is C- Phenol and Formaldehyde.
