Hydrogen molecule is a molecule that releases the most energy when forming its bonds as compared to other molecules.
<h3>What bond needs more energy?</h3>
We know that H-H bond energy is 432 kJ mol-1, CI - CI bond energy is 239kJ mol-1 and Br-Br bond energy is 193 kJ mol-1 so from this data we can conclude that more energy is required to break the bond between hydrogen atom.
