Protonation of 1, 2-butadiene gives carbocation A, and protonation of 2-butyne yields carbocation B. In both cases the most stable carbocation possible is produced, but not carbocation rearrangements take place (no hydride or alkyl shifts). Which of the two carbocations (A or B) is more stable and why?

A and B should be identical.

keshav how are A and B identical? Protonation of 1,2-butadiene yields allyl carbocation while protonation of 2-butyne yields vinyl carbocation. Vinyl carbocations are extremely unstable and allyl carbocations are stabilized by resonance..
