WebThe dissolution of water in octane (C8H18) is principally prevented by ________. A) London dispersion forces between octane molecules. B) repulsion between like-charged water and octane molecules. C) dipole-dipole attraction between octane molecules. D) ion-dipole attraction between water and octane molecules. WebΔH = ∑ΔH ° of bonds broken − ∑ΔH ° of bonds formed. Let’s look at our specific example of the chlorination of methane to determine if it is endothermic or exothermic: Since, the ΔH for the chlorination of methane is negative, the reaction is exothermic. Energetically this reaction is favorable. In order to better understand this ...
