Which of the following carbocations is expected to be the most thermodynamically stable? — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

The triphenylmethyl cation, $(C_6H_5)_3C^+$, is a tertiary benzylic carbocation. Its positive charge is extensively delocalized over three phenyl rings through resonance, making it exceptionally stable compared to primary benzylic or allylic carbocations.
