PVC stands for?

PVC stands for?

• A. Polyvinyl Carbide
• B. Polyvinyl Chloride
• C. Polyethylene Vinyl Chloride
• D. Polyvinyl Chloride Chloride

Answer: (B)

PVC stands for Polyvinyl Chloride. Here, poly means many units, vinyl refers to the vinyl group derived from vinyl chloride monomer, and chloride indicates the chlorine atom that remains in every repeating unit of the polymer. The polymer forms from vinyl chloride (CH2=CHCl) linking into long chains, resulting in the repeating unit [-CH2-CHCl-]n. This composition gives PVC its durable, chemically resistant characteristics, and its rigidity can be adjusted with plasticizers. The other options don’t fit: Polyvinyl Carbide would suggest carbide-related chemistry not present in PVC. Polyethylene Vinyl Chloride isn’t the standard naming for PVC, as it would imply a different or mixed polymer. Polyvinyl Chloride Chloride is redundant, since chlorine is already specified in the correct term.
