Which of the following carbocations derive a significant portion of their thermodynamic stability di — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Allyl and benzyl carbocations have adjacent $\pi$ systems allowing the empty p-orbital to participate in extended delocalization (resonance). Tropylium relies on cyclic delocalization for aromatic stability. Isopropyl carbocation is primarily stabilized by hyperconjugation and $+I$, not resonance.
