Question

$ C{H_2} = C{H_2} $ is a ______.
(A) Monomer
(B) Polymer
(C) Isomer
(D) Equimer

Answer 1

Hint: $ C{H_2} = C{H_2} $ is an organic compound. Its chemical name is ethane and it is also known as ethylene. Ethylene is a colourless gas which is flammable in nature. It is the simplest alkene which is found on earth. In order to know about ethylene, we will first understand the terms monomer, polymer, isomer and equimer.

Complete Step By Step Answer:
We know that $ C{H_2} = C{H_2} $ is an organic compound. Its chemical name is ethane and it is also known as ethylene. It is the simplest alkene which is found on earth.
We will first understand the terms monomer, polymer, isomer and equimer.
Monomer- A monomer is the smallest repeating unit of a polymer chain.
Polymer- It is made by the monomeric units when they repeatedly join together.
Isomer- Isomers are molecules which have the same molecular formula but different structures.
Equimer- It does not have any relation with chemical compounds.
So, based on the above definitions, we can see that $ C{H_2} = C{H_2} $ is a monomer because many units of it join together repeatedly to form a polymer known as polyethylene which has many industrial applications.
Hence, the correct option is (A) Monomer.

Note:
Polyethylene is a light, versatile and synthetic resin which is made by the polymerization of ethane or ethylene. It is the most used plastic in the world. It is of two types such as low density polyethylene (LDPE) (branched version), high density polyethylene (HDPE) (linear version) and ultrahigh molecular weight polyethylene.
