The Correct Option is B
Solution and Explanation
Concept:
Polymers are classified based on the mode of polymerization and the number of monomers involved in their formation.
Addition polymers are formed by repeated addition of monomer units without elimination of any small molecule. Condensation polymers are formed through condensation reactions involving elimination of small molecules such as water or ammonia.
A homopolymer is formed from only one type of monomer, whereas a copolymer is formed from two or more different monomers.
Step 1: Classification of Teflon Teflon is polytetrafluoroethylene (PTFE). \[ nCF_2=CF_2 \longrightarrow (-CF_2-CF_2-)_n \] Only one monomer, tetrafluoroethylene, participates in the polymerization. Therefore: \[ \boxed{\text{Teflon is an Addition Homopolymer}} \]
Step 2: Classification of Melamine-Formaldehyde Resin Melamine-formaldehyde resin is produced from two different monomers: Melamine and Formaldehyde The polymerization occurs through condensation with elimination of water molecules. Therefore: \[ \boxed{\text{Melamine-formaldehyde is a Condensation Copolymer}} \]
Final Answer \[ \boxed{\text{Addition Homopolymer ; Condensation Copolymer}} \] Hence the correct option is \[ \boxed{\text{(B)}} \]
