In Zeigler - Natta polymerisation of ethylene, the active species is
1 \(\mathrm{AlCl}_{3}\)
2 \({\rm{E}}{{\rm{t}}_{\rm{3}}}{\rm{Al}}\)
3 \(\mathrm{CH}_{2}=\mathrm{CH}_{2}\)
4 \(\mathrm{Ti}^{4+}\)
Explanation:
Zeigler - Natta catalyst is \(\mathrm{TiCl}_{4}+\mathrm{Et}_{3} \mathrm{Al}\). The active species is \(\mathrm{TiCl}_{4}\) or \(\mathrm{Ti}^{4+}\)
