Consider the Assertion and Reason given below. Assertion (A) : Ethane polymerized in the presence of Ziegler Natta catalyst at high temperature and pressure is used to make buckets and dustbins Reason (R) : High density polymers are closely packed and are chemically inert. Choose the correct answer from the following :

1. Both (A) and (R) are correct and (R) is the correct explanation of (A)
2. Both (A) and (R) are correct but (R) is not the correct explanation of (A)
3. (A) is correct but (R) is wrong
4. (A) and (R) both are wrong

Correct answer: Both (A) and (R) are correct and (R) is the correct explanation of (A)

Solution

The assertion is correct because ethane, when polymerized with a Ziegler-Natta catalyst, produces high-density polyethylene, which is indeed used for making durable items like buckets and dustbins. The reason is also correct as high-density polymers have a tightly packed structure that contributes to their chemical inertness, thus explaining why such materials are suitable for these applications.
