The catalyst used in the manufacture of polythene by the Ziegler process is

Options

A. `TiCl_(4)`
B. `(C_(2)H_(5))Al`
C. a mixture of (1) and (2)
D. `(C_(6)H_(5))Al`

Answer

C

Explanation

Polythene is manufactured by the Ziegler process. Ethylene gas is passed under pressure into a hydrocarbon solvent containing a suspension of `(C_(2)H_(5))_(3)Al+TiCl_(4)` as catalyst at about `70^(circ)C`. It is called the Ziegler-Natta catalyst.
