Question

The catalyst used for the polymerisation of olefins is:

• A. Ziegler Natta catalyst
• B. Wilkinson's catalyst
• C. Pd-catalyst
• D. Zeise's salt catalyst

Answer 1

The correct option is A Ziegler Natta catalyst

Ziegler-Natta catalysts are mixtures of titanium compounds like titanium(III) chloride ($TiC{l}_3$) or titanium(IV) chloride ($TiC{l}_4$) and compounds of aluminium like aluminium triethyl ($Al(C_2{H}_5{)}_3$). They are used in synthesis of polymers of 1-alkenes (alpha-olefins).
