Noun: - A univalent chemical radical derived from ethylene: The vinyl group is a specific arrangement of atoms (CH₂=CH–) that acts as a functional group in organic chemistry. It is the fundamental building block of vinyl polymers, such as polyvinyl chloride (PVC).

Usage

The term "vinyl group" is used specifically in scientific contexts, primarily in chemistry and materials science, to refer to this reactive molecular fragment. - It is typically used as a modifier in compound names (e.g., vinyl chloride, vinyl acetate). - It describes the characteristic unit from which many common plastics are synthesized.

Examples

• Noun:
  • The reactivity of the vinyl group makes it crucial for polymerization reactions.
  • Vinyl chloride is a molecule containing a vinyl group bonded to a chlorine atom.

Advanced Usage

• "Vinyl" (as a standalone term): In common, non-technical usage, "vinyl" often refers to polyvinyl chloride (PVC) plastic or to phonograph records, which were historically made from PVC. This is a material derived from monomers containing the vinyl group.
  • She collects old vinyl records. (Here, "vinyl" refers to the material, not the specific chemical group.)

Variants and Related Words
