Answer: TiCl4 and Al(C2H5)3.
- A TiCl4 and Al(C2H5)3
- B FeCl3 and BF3
- C BF3 and H2SO4
- D TiCl4 and H2O
Correct answer: A. TiCl4 and Al(C2H5)3
Explanation: Ziegler-Natta catalyst consists of a transition metal halide (TiCl4) and an organoaluminium compound (triethylaluminium).
Addition polymerisation simply links monomers containing a double bond with nothing left over, while condensation polymerisation joins two different monomers through a reaction (often forming an ester or amide bond) that releases a small molecule like water at each step.
Concept context
Large molecules made of repeating monomer units. Covers addition and condensation polymerisation, natural and synthetic polymers (nylon, PVC, Bakelite, natural rubber), and their real-world industrial applications.
