Question

Ziegler-Natta Catalyst is used in the manufacture of

• A. Polyacrylonitrile
• B. Terylene
• C. High density polythene
• D. Low density polythene

Answer 1

The Correct Option is C

Step 1: Understand the Ziegler-Natta Catalyst:
The Ziegler-Natta catalyst is a compound used in the polymerization process, primarily in the manufacture of high-density polyethylene (HDPE) and low-density polyethylene (LDPE). It facilitates the polymerization of alkenes and can also be used for producing other types of plastics.

Step 2: Identify the Correct Product of Ziegler-Natta Catalyst:
The Ziegler-Natta catalyst is particularly used in the polymerization of ethylene to produce polyethylene, which can be either high-density or low-density polyethylene depending on the polymerization conditions.

Step 3: Analyze the Options:

• Polyacrylonitrile: This is a synthetic polymer, but it is not produced by the Ziegler-Natta catalyst. It is produced through a different process, so this option is incorrect.
• Terylene: Terylene (also known as polyester) is a synthetic polymer made from terephthalic acid and ethylene glycol. It is not made using the Ziegler-Natta catalyst, so this option is incorrect.
• High density polyethylene (HDPE): This is produced using the Ziegler-Natta catalyst, making this the correct option.
• Low density polyethylene (LDPE): This is also produced using the Ziegler-Natta catalyst under different conditions, so this option is incorrect.

Final Answer:
The correct product made using the Ziegler-Natta catalyst is High density polyethylene (HDPE).
