Text Solution

Verified by Experts

The correct Answer is:
D
High density polythene (or plastic) is prepared by heating ethylene at about 330-250 K, under a pressure of 1-2 atm and in the presence of Ziegler-Natta catalyst.
`nCH_(2)=CH_(2)underset("Ziegler-Natta catalyst")overset(330-350 K, 1-2 atm)to(CH_(2)-CH_(2))n` high density polythen
