B) titanium
C) rhodium
D) zirconium
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. \[nC{{H}_{2}}=C{{H}_{2}}\xrightarrow[TiC{{l}_{4}}+{{({{C}_{2}}{{H}_{5}})}_{3}}Al]{330-350\,K,1-2\,atm}\underset{\text{polyethylene}}{\mathop{{{(-C{{H}_{2}}-C{{H}_{2}}-)}_{n}}}}\,\]
