Identify the correct statement(s) regarding carbenes: — Reaction Mechanism Chemistry Question

💡 Solution & Explanation

Singlet carbene has paired electrons in a single orbital, allowing stereospecific concerted addition. Triplet carbene behaves as a diradical, resulting in non-stereospecific addition. Photolysis of diazomethane yields singlet carbene initially, which can collisionally decay to the more stable triplet state.
