Question

out of benzyl and tertiary butyl carbocation which one ia more stable and why?​

Answer 1

Answer:

The data is that benzyl cation [PhCH2]+ is indeed more stable than allyl cation [CH2CHCH2]+ when one measures the gas phase hydride ion affinities in kcal/mol. Benzyl cation is 234 kcal/mol and allyl cation is 256 kcal/mol, so benzyl cation is more “stable” by 22 kcal/mol - that’s a lot of kcal/mol.

Answer 2

Answer:

benzyl carbocation is more stable

Explanation:

this is because carbocations are stabilised by nearby electron donating groups.the stability of carbocation increases as we go from primary to secondary to tertiary .benzyl carbocation is more stable because of delocalization of charge due to resonance of pi electrons in ring
