Structure and Properties of Polymers starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Structure and Properties of Polymers. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 11

A sample of a polymer has a degree of polymerization of 500 and the molar mass of the repeating unit is 28 g/mol. Calculate the approximate molar mass of the polymer.

Describe the difference between homopolymers and copolymers.

Describe the effect of cross-linking on the melting point of a polymer.

Describe the structure and one property of cross-linked polymers.

Describe the structure of a linear polymer and give one example.

Explain the difference between addition polymerization and condensation polymerization.

Explain why branched polymers generally have lower density than linear polymers.

Explain why some polymers are soluble in organic solvents while others are not.

Explain why thermoplastics can be recycled but thermosetting plastics cannot.

Explain why thermosetting polymers cannot be remolded after heating.
