An industrially important example is vinyl chloride precursor to pvc a plastic.
Vinylic vs allylic hydrogen.

Key difference allylic vs vinylic carbons functional groups are very important in understanding the different physical and chemical properties of organic molecules the terms allylic and vinyl carbons indicate whether the carbon atom is bonded directly or indirectly to a double bond in a molecule.
For the love of physics walter lewin.

The name is also used for any compound containing that group namely r ch ch 2 where r is any other group of atoms.
Compound bound to a c bound to a c c so x in c c c x would be an allylic group.
But would the c bound to the 2.
The key difference between allylic and vinylic carbon is that allylic carbon is the carbon.
The key difference between these two structural components is the number of carbon and hydrogen atoms.
Here are my best guesses.

Allylic the conjugate base would be delocalized through the conjugated pi system stabilizing it.
Allyl groups have three carbon atoms and five hydrogen atoms.
Allyl group holds three carbon atoms and five hydrogen atoms on the other hand vinyl group has two carbon atoms and three hydrogen atoms.
Identify the number of allylic and vinylic protons in a molecule 001 duration.
This increases the acidity of an allylic proton.
So i ve never been able to keep these terms straight and i m having trouble finding a clear cut answer.
Vinyl halides have a pka of around 44 depending on the groups attached to the alkene so yeah not acidic at all.
The allylic carbon atom is more reactive than normal.
Allyl form a stable carbocation because of the electron delocalization whereas vinylic carbocations are unstable as they lack p character.

Key difference allyl vs vinyl both allyl and vinyl groups have slightly similar structures with a small variation.
