Differbetween
Allyl group holds three carbon atoms and five hydrogen atoms. Vinyl group has two carbon atoms and three hydrogen atoms. Allylic carbon atom can form stable carbocations due to electron delocalization. Vinylic carbocations are very unstable due to lack of P-character.

Which is more stable allylic or vinylic?
The short answer is Allyl carbonation is more stable than Vinyl carbocation bacuse Allyl carbocation is resonance stabilised where as in case of vinyl carbocation, the positive charge on sp hybridized carbon, which is highly unstable.
What is allyl and vinyl?
Allyl and vinyl are two different organic functional groups. Both have C-C double bonds but in different positions. In vinyl group, C=C is directly attached to the rest of the chain. In contrast to vinyl, allyl group is attached to the rest of the molecule through –CH2 group.
What is an allylic carbocation?
An allylic carbocation is a resonance-stabilized carbocation in each of the two resonance forms of which the formal charge of +1 is on an allylic carbon.
What is a vinyl Carbocation?
Vinylic carbocation: A carbocation in which the carbon atom having the open octet and positive formal charge is part of a carbon-carbon double bond. The carbocation carbon has sp hybridization. ... This carbocation is also a benzylic carbocation.
Which is the most stable carbocation?
Therefore CH3⊕CH2 is the most stable carbocation from among the given carbocations.
Which allylic carbocation is the most stable?
Solution : Due to maximum number of hyperconjugation and delocalisation.
When vinyl and allyl are joined each other we get?
When vinyl & allyl are joined each other, we get penta-1,4-diene, which is Isolated alkadiene.
What is the difference between allyl and alkyl?
Allyl group contains sp3 hybridized allylic carbon atoms and sp2 hybridized vinyl carbon atoms. The allylic carbon atom is more reactive than normal alkanes. An alkyl group is a molecule with the general formula CnH2n+1, where n is integer. ...
What is vinyl position?
Vinylic position: On, or bonded to, the carbon of an alkene. This molecule has four vinylic positions, each marked with *. Lewis structure of vinyl chloride, a vinylic halide. Related terms: Vinyl group, vinylic hydrogen, vinylic carbocation, allylic position, benzylic position, propargylic position. Wikipedia entry.
Which is more stable Benzylic Carbocation or allylic carbocation?
Generally, the benzylic carbocations are more stable than allylic carbocations as they form more number of resonating structures and have less electron affinity.
Why are Vinylic Carbocations unstable?
The instability of a vinyl cation cannot be blamed on its sp2 orbital being very electronegative as the positive charge resides in a p orbital, not an sp2 orbital. The instability derives from the inability of that p orbital to overlap with the the sp2 orbitals of the carbon on the other end of the double bond.
Why is allyl Carbocation more stable than propyl Carbation?
Answer. Inductive effect of ethyl will be higher than that of methyl so carbocation attached to ethyl (3 carbons in total) should be more stable. On the other hand 3 hyperconjugation structures can be drawn for the carbocation attached to methyl (2 carbons in total) and only 2 hyperconjugation structure for the other.
