The total energy ( kcal / mol ) is calculated for interaction different wt. % methanol/ethanol with SnO2 in distance (7.0 Å) at different temperatures by Fig.6. Web3 mei 2024 · In methanol, the hydroxyl group accounts for almost half of the weight of the molecule, and it is not surprising that the substance is completely soluble in water. As the size of the hydrocarbon groups of alcohols increases, the hydroxyl group accounts for progressively less of the molecular weight, hence water solubility decreases (Figure 15-1). grove city oh trick or treat
