Question

Tropylium cation is more stable than triphenylmethyl carbocation why

Answer 1

Answer:

The tropylium cation is more stable than triphenylmethyl carbocation. This is so because tropylium cation is the aromatic compound.

Explanation:

The aromatic compound is defined as the compounds that obey the Huckel's rule. The tropylium cation is the aromatic compound because it satisfies the Huckel's rule. The cation of the tropylium undergo resonance with pi bond and make the compound aromatic whereas, in the tropylium cation, the cation undergo cross resonance with pi bonds of three phenyl compound so, the overlapping of the pi orbitals is not perfect because of the steric hindrance force.

Hence, the tropylium cation is more stable than triphenylmethyl carbocation.
