Question

    Bakelite is a polymer which is used in the manufacturing

    of buckets and electrical switches. What are the monomers of bakelite?
    A Phenol and formaldehyde Correct Answer Incorrect Answer
    B 1, 3 butadiene and styrene Correct Answer Incorrect Answer
    C Ethylene glycol and terephtalic acid Correct Answer Incorrect Answer
    D Chloroprene Correct Answer Incorrect Answer

    Solution

    A polymer is formed from monomer units. Bakelite is a polymer formed from phenol and formaldehyde (which are monomers). Bakelite is an early plastic. It is a thermosetting polymer (thermosetting plastics remain in a permanent solid state once hardened) formed from condensation of phenol and formaldehyde. Neoprene is the polymer of chloroprene. Polyethylene terephthalate is the polymer of ethylene glycol and terephtalic acid. Buna –S is the polymer of 1, 3 buta diene ad styrene. Hence, option A is correct.
