Question
what is the role of hydrogen bond formation betwwen water, assolvent, and a compound placed in water(a solute, or a potentialsolute)? A. H bonding by water has no role in dissolving anysolutes. B. the number of H bonds that can form between water and asolute (or potential solute) determines the solubility of acompound in water. C. The number of H bonds with water, compared to the totalsize of the porential solute, determines the solubility of acompound in water. D. Its ability to H bond with solutes makes water a "universalsolvent" E/ Hydrogen bonding is responsible for the high solubility ofmethane in water. what is the role of hydrogen bond formation betwwen water, assolvent, and a compound placed in water(a solute, or a potentialsolute)?

For a solute to be soluble in a solvent, three events musthappen: (1) The breaking of bonding between the solute (2) The breaking of bonding between the solvent (3) The formation of bonding betwene solute and solvent So, if no hydrogen bonding between solute and solvent (eg: inhydrophobic compound), the solute will not be soluble and will formprecipitate. This is known as the hydrophobic effect, which is thetendency of water to exclude the hydrophobic compound. Thus, thenumber of hydrogen bond can form between the water and solutedetermines the solubility of a compound in water. (B) is the mostappropriate answer Hope this helps!
