Weekly Quiz Competition

Question 1
1 / -0

Among the following, the branched chain polymer is:

A
Polyvinyl chloride

B
Bakelite

C
Low density polythene

D
High density polythene

Solution

Low-density polythene is a branched-chain polymer made from the monomer ethylene.

Hence, option C is correct.
Question 2
1 / -0

Which is the correct structure of Nylon-6?

A

B

C

D

Solution

Nylon-6 will be derived from the $$\epsilon$$-caprolactum which contain 6 carbon atoms.
Question 3
1 / -0

Orlon is a polymer of

A
Tertafluoro ethylene

B
Acrylonitrile

C
Ethanoic acid

D
Benzene
Question 4
1 / -0

Which of the following polymer is used in paints?

A
Gutta percha

B
Melamine

C
Buna-S

D
Novolac

Solution

Gutta-percha is trans-1,4-polyisoprene. It is generally used in root canal obturating material.

Buna-S is a polymer of 1,3-butadiene and styrene and it is used to make gaskets, tires, etc.

Melamine is a polymer of melamine and formaldehyde and is used to make plastic materials.

Novolac is a condensation polymer of formaldehyde and phenol and it is used in paints.

Hence, option $$D$$ is correct.
Question 5
1 / -0

In bakelite, the rings are joined to each other through:

A
$$ -CH_2- $$

B
$$ -O- $$

C

D

Solution
Question 6
1 / -0

A plastic bakelite is a compound of phenol with:

A
$$ CH_3CHO $$

B
$$ HCHO $$

C
acetal

D
chlorobenzene

Solution
Question 7
1 / -0

Polymers 'X' and 'Y' respectively are:

A
nylon-6; nylon-6, 6

B
nylon-6,6; nylon-6

C
nylon-6; nylon-6, 10

D
nylon-6,6; nylon-6, 10

Solution

Nylon-x,y is a nylon polymer formed by the reaction of a diammine of x carbons and a dibasic carboxylic acid of y carbons.

Therefore, the product formed on the reaction of $$\mathrm{NH_2-(CH_2)_6-NH_2}$$ and adipic acid $$\mathrm{COOH-(CH_2)_4-COOH}$$ is Nylon-6,6

and, the product formed on the reaction of $$\mathrm{NH_2-(CH_2)_6-NH_2}$$ and sebaic acid $$\mathrm{COOH-(CH_2)_8-COOH}$$ is Nylon-6,10

Hence, Option "D" is the correct answer.
Question 8
1 / -0

Which of the following statements is not correct?

A
Caprolactam is the monomer of nylon-6

B
Terylene is a polyester polymer

C
Phenol formaldehyde resin is known as bakelite

D
The monomer of natural rubber is butadiene

Solution

Caprolactam is the monomer of nylon-6.
Terylene is a polyester polymer.
Phenol formaldehyde resin is known as bakelite.
The monomer of natural rubber is isoprene.

Hence, Option "D" is the correct answer.
Question 9
1 / -0

The monomer of polystyrene is:

A
$$C_2H_5CH=CH_2$$

B
$$CH_2=CHCl$$

C
$$C_6H_5CH=CH_2$$

D
$$CH_2=CHCHO$$

E
$$C_6H_5CH=CHCHO$$

Solution

The monomer of polystyrene is Styrene i.e. $$\mathrm{C_6H_5CH=CH_2}$$
Hence, Option "C" is the correct answer.
Question 10
1 / -0

Bakelite is prepared by the reaction between:

A
phenol and formaldehyde

B
urea and formaldehyde

C
ethylene and glycol

D
tetramethylene and glycol

Solution

correct answer : A
Bakelite is the commercial name for the polymer obtained by the polymerization of phenol and formaldehyde. These are one of the oldest polymers that were synthesized by man. Phenol is made to react with formaldehyde.

Also Bakelite is a polymer obtained by the condensation reaction between phenol and formaldehyde. It is a condensation polymer and basic unit of Bekelite is Novolac.
