How many equivalent resonance structures can be written for the cycloheptatrienyl cation?

Question

Quizplus · Accepted Answer

The cycloheptatrienyl cation, also known as the tropylium ion, has 7 equivalent resonance structures. This is because the positive charge and the double bonds can be delocalized around the seven-membered ring, allowing for 7 different but equivalent ways to draw the structure with the double bonds and positive charge in different locations.
