Question Statement: Which of the above is less stable and more reactive? Relevant Equations: None really. Attempt at solution: Well, the C-O bond's bond energy is lower so I argued that since it takes less energy to break this bond than it does to break the C=C double bond, then it (C-O) is less stable and more reactive. Is the correct or am I wrong in making that assumption? Apologies for the lack of a proper layout. Sending this from my phone.
