NEET Chemistry Surface Chemistry Questions Solved


In Zeigler-Natta polymerisation of ethylene, the active species is:

(1)AlCl3

(2)Et3Al

(3)CH2CH2

(4)TiIII

 

 

 

 

(a)Zeigler-Natta catalyst is formed by the action of (C2H5)3Al and TiCl4. the active species is (C2H5)3Al  can reduce TiCl4 to TiCl3. TiIII has one active site vacant and thus accommodates one alkyl group
