Question

Q7. The polymer containing different monomer
units is called
(A) Homopolymer
(B) Addition polymer
(C) Condensation polymer
(D) Copolymer​

Answer 1

Answer:

● The polymer containing different monomer units is called Copolymer.

Answer 2

Answer:

The polymer is containing different types of monomer units is called copolymer.

Therefore, the option (D) is correct.

Explanation:

• The simple molecules from which repeating structural units are derived is called monomers. The process of formation of polymer from the monomer is called polymerization.
• A polymer which is obtained from only one type of monomer is called Homopolymer. For example, polyethylene.
• A polymer made of two or more type of monomer is called copolymers. For example. nylon 66.
• Addition polymerization is in which large number of molecules are added together for the formation of large polymeric molecule. The polymer obtained by it is called addition polymer.
• The polymerization in which the monomer molecules are combine together in a stepwise manner with the elimination of simple molecules is called condensation polymerization. The polymer obtained is called condensation polymer.
