Question
What is a polymer and how is it formed?
Answer
A polymer is a large molecule made up of repeating units called monomers, which are covalently bonded together. Polymers are formed through a process called polymerization, where many small molecules (monomers) join together to create a larger structure.
Explanation
This answer is strong because it defines a polymer and explains its formation process, directly addressing the learning objective about recognizing covalent substances that form large molecules. It tests the student's understanding of the concept of polymers in chemistry.
Common mistake
Misunderstanding Polymer Size
Students often think that all covalent substances are small molecules and do not recognize that some can form very large structures like polymers.
Emphasize that polymers are large molecules made of repeating units, and practice identifying examples of both small molecules and polymers.
