Easy

Which of the following is a thermosetting polymer?

A. Epoxy resin

B. Polyethylene

C. Polystyrene

D. Polyvinyl chloride

Show Answer & Explanation

Correct Answer: A

Epoxy resins are thermosetting polymers that harden upon curing, unlike thermoplastics which can be re-melted.

Easy

Polyethylene is classified as a:

A. Addition polymer

B. Condensation polymer

C. Natural polymer

D. Biopolymer

Show Answer & Explanation

Correct Answer: A

Polyethylene is formed by the addition of ethylene monomers, making it an addition polymer.

Easy

Which of the following is an example of a natural polymer?

A. Nylon

B. Cellulose

C. Polystyrene

D. Polypropylene

Show Answer & Explanation

Correct Answer: B

Cellulose is a natural polymer found in the cell walls of plants.

Medium

Which of the following polymers is classified as a thermoplastic?

A. Polyethylene

B. Bakelite

C. Nylon

D. Natural Rubber

Show Answer & Explanation

Correct Answer: A

Polyethylene is a thermoplastic, meaning it can be melted and reshaped. Bakelite is a thermoset, while Nylon can be classified under both but primarily is a thermoplastic.

Medium

What type of polymer is formed from the polymerization of glucose?

A. Cellulose

B. Polystyrene

C. Polyvinyl Chloride

D. Teflon

Show Answer & Explanation

Correct Answer: A

Cellulose is a polysaccharide formed from glucose units, while the others are synthetic polymers.

Medium

Which of the following is NOT a characteristic of elastomers?

A. Low elasticity

B. High flexibility

C. Low density

D. Resilience

Show Answer & Explanation

Correct Answer: A

Elastomers are known for their high elasticity, making 'low elasticity' an incorrect characteristic.

Medium

Which of the following is an example of a condensation polymer?

A. Polyethylene

B. Polyester

C. Polypropylene

D. Polystyrene

Show Answer & Explanation

Correct Answer: B

Polyester is formed through condensation polymerization, where small molecules are released during polymer formation.

Hard

Which type of polymerization involves the reaction of monomers that contain a functional group with one another?

A. Addition Polymerization

B. Condensation Polymerization

C. Copolymerization

D. Cross-linking

Show Answer & Explanation

Correct Answer: B

Condensation polymerization involves the reaction of monomers with functional groups where a small molecule, like water, is eliminated.

Hard

Which of the following is NOT a characteristic of thermoplastic polymers?

A. Can be remolded

B. Has a fixed shape

C. Softens on heating

D. Linear or branched structure

Show Answer & Explanation

Correct Answer: B

Thermoplastics do not have a fixed shape; they can be reshaped when heated, unlike thermosetting polymers which maintain a fixed shape.

Q10

Hard

Which of the following polymers is classified as a condensation polymer?

A. Polyethylene

B. Nylon-6

C. Polystyrene

D. Polypropylene

Show Answer & Explanation

Correct Answer: B

Nylon-6 is a condensation polymer formed by the reaction of amino acids, releasing water during polymerization.
