Question

Most compounds containing the benzyl group produce a peak at m/z 91 corresponding to the tropylium ion.Explain why tropylium cation is very stable.

Accepted Answer

The stability of the tropylium cation is due to the resonance that results in the positive charge being stabilized over seven carbon atoms.

Answer

The stability of the tropylium cation is due to the resonance that results in the positive charge being stabilized over five carbon atoms.

Answer

The stability of the tropylium cation is due to the resonance that results in the positive charge being stabilized over six carbon atoms.

Answer

The stability of the tropylium cation is due to the resonance that results in an unpaired electron being stabilized over seven carbon atoms.
