A) iron
B) titanium
C) rhodium
D) ziroconium
Correct Answer: B
Solution :
Ziegler Natta catalyst is an organometallic compound containing titanium. It is\[TiC{{l}_{4}}\]and\[{{({{C}_{2}}{{H}_{5}})}_{3}}Al\]. It is used in the preparation of polyethylene. \[nC{{H}_{2}}=C{{H}_{2}}\xrightarrow[TiC{{l}_{4}}+({{C}_{2}}{{H}_{5}})Al]{330-350\,K,\,1-2\,atm}\underset{Polyetylene}{\mathop{{{(-C{{H}_{2}}-C{{H}_{2}}-)}_{n}}}}\,\]
