‘PVC’ is a high strength thermoplastic material widely used in applications, such as pipes, medical devices, wire and cable insulation. What is the full form of PVC?

Polyvinyl Chloride

The correct answer is option 2. Polyvinyl Chloride.

Polyvinyl chloride (PVC) is a type of thermoplastic polymer. Let's break down its full form:

1. Poly: This prefix indicates that PVC is a polymer, meaning it is composed of repeating units of smaller molecules called monomers. In the case of PVC, the monomer is vinyl chloride.

2. Vinyl: This part refers to the vinyl group $(CH_2=CH^-)$, which is a functional group consisting of two carbon atoms linked by a double bond to one carbon atom. Vinyl groups are characteristic of many organic compounds, including vinyl chloride, the monomer from which PVC is derived.

3. Chloride: This refers to the chlorine atom (Cl) present in the vinyl chloride monomer. During polymerization, the chlorine atom is incorporated into the polymer chain, giving PVC its distinctive properties.

So, when these elements are combined, the full form "Polyvinyl Chloride" indicates a polymer composed of repeating vinyl chloride units linked together. PVC is known for its versatility, durability, and resistance to chemicals, making it suitable for various applications such as pipes, medical devices, wire and cable insulation, flooring, packaging, and more.
