Chemical species bearing a positive charge on carbon and carrying six electrons in its valence shell are called carbocations. The product is then formed by nucleophilic attack at the new, more stable carbocation.
Which Carbocation Is Most Stable. What this means is that, in general, more substituted carbocations are more stable: As we all know, the carbocation will be the most stable if the carbocation is most substituted. The more resonance structures you can draw, that is the carbocation more stable. Because the hydride took the bond electrons, the carbon where the h migrated from becomes the new carbocation.

The question is which among the fallen car walk then, is the most stable part. But carbocation #5 is vinylic carbocation. >>which allylic carbocation is the most st. I have read that resonance is the biggest deciding factor about the stability of a carbocation but some argue that (a) would be most stable as it is farthest away from a highly electronegative chlorine atom.
Which carbocation is most reactive?
In the first question, the most stable carbocation is the one in which the positive charge is on a tertiary carbon atom, because a tertiary carbocation is more stable than primary or secondary carbocation, because of the electron donatind tendency of the methyl groups. So, the tertiary carbocation is the most stable, and the least is the methyl carbocation. The product is then formed by nucleophilic attack at the new, more stable carbocation. According to me the answer should be (c) as that carbocation will be stablized by resonance with chlorine. We have simples second, we have c six s five cs two plus. This car book today is the most stable mind because this car is the signal providing intel, carved wooden in the signal profiled metal car boudin number of the ordinance are very high.

Allylic carbocation is more stable than the substituted alkyl carbocation due to the delocalization relation of the resonance interaction between the carbon bearing the positive charge and the pie bond present next to it. Further out of (b) and (d), (d) has less angular strain and as such is more stable. The general stability order of simple alkyl carbocations is:

If you take away one thing from this post, it should be that the more alkyl groups we add to a carbocation, the more stable that carbocation is: This is because alkyl groups are weakly electron donating due to hyperconjugation and inductive effects. Tertiary carbocations are more stable than primary or secondary carbocations because they have three methyl groups to distribute it�s positive charge rather than only one or two methyl groups.
