This set of Applied Chemistry Multiple Choice Questions & Answers (MCQs) focuses on “Types of Polymers”.
1. The polymers are classified into _________ types based on the nature of polymerization.
a) 5
b) 2
c) 3
d) 4
View Answer
Explanation: The polymers are classified into two types based upon their nature of polymerization. They are homopolymers and co polymers.
2. A straight chain polymer comes under the _________ type of the polymers.
a) Homo polymers
b) Co-polymers
c) Regular chain copolymers
d) Irregular straight chain copolymers
View Answer
Explanation: The straight chain polymers come under the homo polymers. The regular straight chain copolymers and irregular straight chain copolymer comes under the straight chain copolymers.
3. The different monomers are arranged alternatively in __________
a) Alternate straight chain polymers
b) Regular straight chain copolymers
c) Straight chain copolymer
d) Cross linked polymers
View Answer
Explanation: The different monomers are arranged alternatively in alternate straight chain polymers. The regular straight chain polymers the monomeric units arranged regularly.
4. The polymers whose backbone is made of same type of atoms called ___________
a) Homo polymers
b) Heterochain polymers
c) Isotactic polymers
d) Atactic polymers
View Answer
Explanation: The polymers whose back bone is made of some type of atoms is called as homopolymers. The heteropolymers backbone is constructed by the two or more than two different types of atoms.
5. Tacticity of the polymers is the arrangement of the ___________ on carbon backbone.
a) Hydrogen atoms
b) Nitrogen atoms
c) Functional groups
d) Carbons
View Answer
Explanation: The tacticity is defined as the arrangement of the function groups on the carbon back bone of the polymer is called tacticity of the polymer.
6. Based on tacticity, the polymers are divided into __________ types.
a) Two
b) Three
c) Four
d) Five
View Answer
Explanation: Based on tacticity, the polymers are divided into three types. They are Isotactic polymers, Atactic polymers and syndiotactic polymer.
7. The functional group are arranged on the same side of the carbon back bone are said to be _________
a) Syndiotactic polymers
b) Atactic polymers
c) Isotactic polymers
d) Chain polymers
View Answer
Explanation: The functional groups arranged on the same side of the carbon back bone then it is isotactic polymer, if they no regular arrangement then they are said to be Atactic polymers.
8. Which of the following is the example of the syndiotactic polymers?
a) Poly propylene
b) Poly vinyl chloride
c) Gutta percha
d) Poly lactic acids
View Answer
Explanation: The gutta percha is the natural form of rubber. It is the example of the syndiotactic polymers in which the functional groups are alternately arranged. Poly propylene and poly lactic acids are the examples of the isotactic polymers.
9. Alternate straight chain polymers are ___________
a) Soft and flexible
b) Hard and flexible
c) Soft and brittle
d) Hard and brittle
View Answer
Explanation: Alternate straight chain polymers are soft and brittle nature. All the straight chain polymers are soft and brittle.
10. Combination of the organic and inorganic polymers are called _________
a) Element organic polymers
b) Inorganic polymers
c) Fibres
d) Thermoplastics
View Answer
Explanation: Combination of the organic and the inorganic polymers are called as the element of organic polymers. It comes under the synthetic polymers because it is produced by the synthesis.
