Question

Predicting Solubilities Decide which compound will be more likely to dissolve in the given liquid. Think about the IMF between the solvent and each solute. 1. Solvent: methanol (CH3OH) Solutes: carbon diselenide and oxygen dichloride - 2. Solvent: carbon disulfide Solutes: methanol (CH3OH) and lithium chloride 3. Solvent: water Solutes: carbon tetrachloride and ammonia

Answer 1

ac non Dolar (non polar) dipole IMA Like dissolves like is the principle of solubility. ie Polar compounds dissolve in polar solvents and non polar compounds dissolved in non polar solvents. 1. Solvent CHOH polar solvent); forms H-bonds. solutes : Carbon di selenide (C Condon force) Oxygen dichloride (oc) polar) (dipole na Och is more polar than cse, Hence oxygen dichloride is more soluble in CH OH. 3 Solvent Carbon di sulfide (CS): Non polar. (London force) Solute: CLOH (polar covalent) ; dipole-dipole in Licl, Jonic compound with covalent character. Lich is more polar than ChOH. Hence Lithiun aloride is a Methand which is less polar is more soluble in c 3) Solvent: Water & Polar, forms H-bonds solute: ccl non polar, IMF is London force only With polar, forms t-bonds. NH is more soluble in water. ms
