Explanation
To determine which organic compounds polymerize to form the polyester Dacron, we need to understand the chemical structure of Dacron.Dacron is a type of polyester, specifically polyethylene terephthalate (PET).It is formed by the polymerization of two monomers: terephthalic acid and ethylene glycol.Let's analyze the options:Option 1: Propylene and paraโHOโ(C6โH4โ)โOH
