Question

The Nobel-prize-winning Ziegler-Natta catalyst revolutionized the plastics industry by enabling the stereospecific polymerization of terminal alkenes (like ethene to high-density polythene). What is the exact chemical composition of this heterogeneous catalyst system?

Prashant Kotian · Accepted Answer

Correct answer: B. The Ziegler-Natta catalyst is a highly specific, two-part coordination catalyst. It universally consists of a transition metal halide—primarily Titanium(IV) chloride ()—combined with a main-group organometallic co-catalyst like Triethylaluminium or Trimethylaluminium.
