    In Ziegler-Natta polymerisation of ethylene, the active species is

    A)  \[AlC{{l}_{3}}\]                                

    B)  \[TiC{{l}_{4}}\]

    C)  \[E{{t}_{3}}Al\]                

    D)  \[Ti(III)\]

    Correct Answer: D

    Solution :

                    Ziegler-Natta catalyst is a mixture of \[TiC{{l}_{4}}\] and \[Al{{({{C}_{2}}{{H}_{5}})}_{3}}\] which react to produce fibrous form of \[TiC{{l}_{3}}\] (an active metal species).
