Question 1
1 / -0

The structure of Nylon-6 is:

A

B

C

D

Solution

Solution:- (C)
The structure of Nylon-$$6$$ is:
$${\left[ -\overset{\underset{||}{O}}{C}-{\left( C{H}_{2} \right)}_{5}-\overset{\underset{|}{H}}{N}- \right]}_{n}$$
Question 2
1 / -0

Which one of the following is a polyamide polymer?

A
Terylene

B
Nylon-6

C
Buna-S

D
Bakelite

Solution

Nylon is a polyamide polymer characterized by the presence of amide groups in the main polymer chain.

Nylon 6 is produced from caprolactam by ring-opening polymerization.

Since caprolactam contains six carbon atoms and only one monomer is used, the polymer is thus designated as nylon 6.

Hence, option B is correct.
Question 3
1 / -0

Polymer is:

A

B

C

D

Solution

In the given polymerization reaction, first the reactant undergoes $$\beta$$- elimination reaction to form our monomer.
This monomer then undergoes polymerization to form corresponding polymer.
Question 4
1 / -0

Which polymer is used in non-stick cooking vessels ?

A
Polythene

B
Isoprene

C
Teflon

D
Neoprene

Solution

Teflon, which is the trade name for Polytetrafluoroethylene (PTFE), is the polymer used to deposit non-stick coatings on cookware.
Question 5
1 / -0

The biodegradable polymer is:

A
Nylon -6,6

B
Nylon -2-Nylon 6

C
Nylon -6

D
Buna-S

Solution

Nylon-2-Nylon 6 is a Biodegradable polymer.

Option B is correct.
Question 6
1 / -0

Which polymer is obtained in the following sequence of reactions?
$$CHCl_3 \xrightarrow[SbF_3]{HF} X \xrightarrow{800^0C} Y \xrightarrow{polymerization} \underset{(Polymer)}{Plastic}$$

A
Bakelite

B
Teflon

C
Polythene

D
Nylon-6, 6

Solution

Polytetrafluoroethylene, also known as Teflon is made with four ingredients -- fluorspar, hydrofluoric acid, chloroform, and water, which are combined in a chemical reaction chamber heated to between $$1094-1652^0F (590-900^0C$$
so the given reaction is forming teflon
Given B is correct answer
Question 7
1 / -0

Rubber is a:

A
conducting polymer

B
oriented polymer

C
elastomer

D
strong commercial fabric

Solution

Rubber is a material which can stretch and shrink. It is a polymer. Sometimes the word means only natural rubber (latex rubber). Natural rubber is made from the white sap of some trees such as the Hevea brasiliensis (Euphorbiaceae). Other elastomers, called synthetic rubbers, are made by chemical processes.
Question 8
1 / -0

What substance is formed when $$F_2C = CF_2$$ is polymerized?

A
Polyethylene

B
Polyurathene

C
PVC

D
Teflon

Solution

When Tetrafluoro ethane is polymerised, poly tetrafluoro ethane is formed which is also known as Teflon.
Hence, Option "D" is the correct answer.
Question 9
1 / -0

Teflon is a polymer of :

A
ethylene

B
vinyl chloride

C
acetonitrile

D
tetrafluoroethene

Solution

Teflon is a polymer of tetrafluoroethene. It is an excellent plastic material for films and coatings.
Question 10
1 / -0

Chemical reactions could have converted simple organic compounds into _________ for origin of life:

A
Macromolecules

B
Cells

C
Nitrogen

D
Micromolecules

Solution

Life originated by chemosynthesis i.e., synthesis of organic bio-molecules from inorganic compounds through chemical processes. In the primitive earth, biological catalysts were absent and organic bio-molecules could have evolved from inorganic molecules through chemical synthesis and chemical reactions could have converted simple organic compounds into macromolecules.
So the correct answer is option A.
