Which is expected to have the most negative standard enthalpy of formation?

Question

Quizplus · Accepted Answer

Generally, the standard enthalpy of formation becomes more negative as the number of bonds formed increases. The presence of oxygen atoms in a molecule can also lead to a more negative standard enthalpy of formation due to the high electronegativity and the ability to form strong bonds. Therefore, the molecule with the most bonds and oxygen atoms, which is H₂O(l), is expected to have the most negative standard enthalpy of formation.
