Organic Polymers and Biopolymers 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 Organic Polymers and Biopolymers. 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 12

Explain why proteins have a specific three-dimensional structure.

A biodegradable polymer is synthesized from glycolic acid and lactic acid. Name this polymer and describe one of its major applications in the medical field.

A certain synthetic polymer is produced by the free radical polymerization of methyl methacrylate. Name the resulting polymer and describe one of its common uses.

A sample of a synthetic polymer has a number average molecular mass (Mₙ) of 30,000 g/mol and a weight average molecular mass (M_w) of 60,000 g/mol. Calculate the polydispersity index (PDI) and explain what this value indicates about the polymer sample.
