Vinyl-group-reactions, in chemistry, vinyl or ethenyl is the functional group with the formula −ch=ch2. it is the ethylene molecule with one fewer hydrogen atom. the name is also used for any compound containing that group, namely r−ch=ch2 where r is any other group of atoms. an industrially important example is vinyl chloride, precursor to pvc, a plastic commonly known as vinyl. chessboard made from polyvinyl chloride vinyl is one of the alkenyl functional groups. on a carbon skeleton, sp2-hybridized carbons .... We investigated the adsorption of vinyl alcohol onto ge(100) surface by performing density functional theory calculations. the c–o dissociative adsorption of vinyl alcohol produces two fragments, a hydroxyl group and a vinyl group, each of which bonds with a different germanium atom., evidence of unequal vinyl group reactivity in copolymerization/crosslinking reactions of mono- and divinyl comonomers antonios g. mikos, christosg..
