Question
- A. Addition polymers are always biodegradable, while condensation polymers are not
- B. Addition polymers do not involve the loss of small molecules, while condensation polymers do
- C. Addition polymers can only be made from alkenes, while condensation polymers can be made from any monomer
- D. Addition polymers have a lower molecular weight than condensation polymers
Answer
Addition polymers do not involve the loss of small molecules, while condensation polymers do
Explanation
The primary difference between addition and condensation polymers is that addition polymers are formed without the loss of small molecules, while condensation polymers involve such loss during their formation. This distinction is crucial in understanding the mechanisms of polymerization and the types of products formed. Addition polymers are relevant in the context of materials like polyethylene, while condensation polymers are seen in products like nylon.
Common mistake
Distinguishing Addition and Condensation Polymers
Students often confuse addition polymers with condensation polymers, thinking they are the same because both involve multiple monomers.
Addition polymers are formed through the addition of unsaturated monomers (like alkenes) without the loss of any small molecules, while condensation polymers are formed by the reaction of monomers with the loss of small molecules (like water). Remember that addition polymers involve only C=C bonds, whereas condensation polymers involve functional groups that can react to release small molecules.
