Question

Identify homopolymer from following.

• A. Teflon
• B. Nylon 2-nylon 6
• C. PHBV
• D. Bakelite

Hint:

The prefixes in polymer names often give away their nature! Names with multiple chemical parts (like Phenol-Formaldehyde or Nylon-6,6) are copolymers. Simple repeating names (like Poly-ethylene, Poly-propylene, Poly-tetrafluoroethylene) are homopolymers!

Answer 1

The Correct Option is A

Step 1: Define homopolymer.
A homopolymer is built from just one kind of repeating unit. If two or more units are used, it is a copolymer.

Step 2: Check each polymer.
Nylon 2-nylon 6, PHBV and Bakelite each use two different starting units, so they are copolymers.

Step 3: Find the single unit one.
Teflon is made only from tetrafluoroethylene, so it is the homopolymer.
\[ \boxed{\text{Teflon}} \]
