    What is the bond energy of the C=O bond? ________ - ProProfs

    What is the bond energy of the C=O bond? ________

    Correct Answer
    841,+841
    Explanation
    The bond energy of the C=O bond is 841 kJ/mol. This indicates the amount of energy required to break one mole of C=O bonds. The positive sign indicates that this is an endothermic process, meaning energy is absorbed when the bond is broken. The repetition of +841 suggests that this bond energy is consistent and reliable.
