Question

2 Answer the following.
1) Write the name of Alkene used in the manufacture of polythene bags.
2) What are the main natural sources of Alkane ?​

Answer 1

Answer:

1 Polyethene

Explanation:

Polyethene is made by addition polymerization of ethene, which is principally produced by the cracking of ethane and propane, naphtha and gas oil. Polyethene is used to manufacture polythene bags.

Answer 2

The answers to your questions are as follows:

Explanation:

1. Ethane is a kind of Alkene that is used to make polythene bags.
2. A process known as cracking produces alkenes from the alkanes in crude oil. Heat and a catalyst are used to break down alkanes in cracking.

• The cracking process is significant because it converts less usable alkanes into smaller, more useful alkenes like ethane, which is the starting ingredient for many polymers. By shaking the hydrocarbon with bromine water, an alkene can be differentiated from an alkane.
