WebCorrect answers: 2 question: Most solids increase their water solubility with decreasing temperature. g The more hydroxyl (OH) groups on an alcohol, the less soluble it is in water. Gas solubility increases as the partial pressure of the gas (over the solvent) decreases. The solubility of liquid alcohols in water decreases as the number of carbon atoms in the … WebHydroxyl groups are polar, turn molecules into alcohols, and allow molecules to dissolve in water. Carboxyl groups can donate hydrogen ions, so they make molecules acidic. Amino groups can pick up hydrogen ions from the surroundings, so they make molecules basic. Other functional groups include sulfhydryl, carbonyl, methyl, and phosphate groups. toy shops aberdeen city centre

WebThe hydroxyl group (-OH) present is polar, and the alkyl (R) group present is non-polar. The physical properties of an alcohol depend on whether the polar or the non-polar portion of its structure “dominates”. Factors that determine this include the length of the non-polar carbon chain present and the number of the polar hydroxyl group present. WebProblem. Answer true or false.
