The key difference between a vinylic carbon and an allylic carbon is their location in a molecule. A vinylic carbon is directly attached to a double bond, while an allylic carbon is next to a double bond. Allylic carbons are more reactive and have different chemical properties compared to vinylic carbons due to the presence of the double bond next to them.

The presence of an allylic lone pair in a molecule can increase its reactivity by making it more susceptible to nucleophilic attacks or electrophilic reactions due to the electron-rich nature of the lone pair. This can lead to enhanced reactivity in certain chemical reactions.
Allylic compounds have a carbon-carbon double bond next to a carbon-carbon single bond, while vinylic compounds have a carbon-carbon double bond directly attached to a carbon atom. Allylic compounds are more stable and less reactive than vinylic compounds due to the presence of the single bond, which provides additional stability. Vinylic compounds are more reactive and undergo addition reactions more readily than allylic compounds.

Vinylic compounds are more reactive and undergo addition reactions more readily than allylic compounds.
Vinylic functional groups have a double bond directly attached to a carbon atom, while allylic functional groups have a double bond attached to a carbon atom that is next to a carbon-carbon double bond. This difference affects their reactivity and stability in organic reactions.
An allylic carbocation is a positively charged carbon atom that is located next to a carbon-carbon double bond. It is more stable than a regular carbocation because of resonance delocalization. Allylic carbocations are reactive and can undergo various reactions, such as nucleophilic attack and rearrangement, due to their electron-deficient nature.
