WebMar 22, 2024 · When HF is dissolved in water, the ${{H}_{2}}O$ molecules get oriented around the HF molecule through hydrogen bonding and stabilize it. Thus, we can say that no dative bond is involved in this case. (C) Dimerisation of benzoic acid: Hydrogen bond is involved in the dimerisation of benzoic acid because the H atom of one acid molecule … WebThat's their heats of formation. So Hess's Law tells us that delta H of this reaction, the change in enthalpy of this reaction, is essentially going to be the sum of what it takes to decompose these guys, which is the minus heat of formations of these guys, plus what it takes to reform these guys over here. So we can just write it as delta H of ...
