MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

Teflon is the commercial name for polytetrafluoroethylene (PTFE). The monomer of Teflon is tetrafluoroethylene, which has the chemical formula CF_2=CF_2. Since all the hydrogen atoms in the ethylene monomer are replaced by fluorine atoms, Teflon is a fully fluorinated polymer. PVC (polyvinyl chloride) contains chlorine and hydrogen, neoprene contains chlorine and hydrogen, and Buna-S is a hydrocarbon polymer containing only carbon and hydrogen. Answer: Teflon
