Question

Cycloheptatrienyl cation is more stable than methyl benzene cation because

Answer 1

Answer:

The cycloheptatrienyl cation has several resonance structures, so the charge can be delocalized over all seven carbon atoms.

In contrast, cycloheptatrienyl anion, has 4n π electrons (n = 2), and is unusually unstable. It, too, is antiaromatic

Answer 2

Explanation:

1) Benzyl carbonium ion is more stable than ethyl carbonium ion because of resonance in benzyl carbonium ion. 2) Out of these two, BF3 is more acidic than BCl3. ... It is more stable than ethyl cation because in allyl cation, resonance happens which makes it more stable.
