Hayatcakes Group Title

Compared to other main group hydrides, such as CH4, NH3, H2S and HF, water is unique because it is a liquid at room temperature. The most likely explanation for this is that: Water is more plentiful than any of these other compounds. Water contains oxygen and since oxygen has a high boiling point, so should water. Water's structure allows for the formation of multiple hydrogen bonds with other molecules, including itself. Water is able to dissolve nonpolar gases like oxygen and carbon dioxide.

    can you draw lewis structures for these 5 molecules? that should give you your first clue

    I don't have a diagram but I believe the answer is the third choice?

    It is. In general, the easiest way to predict the differences in properties like BP, MP, and solubility is to compare the lewis structures of the molecules you're being asked about.

    Calculate the freezing point of a 2.6-molal aqueous sucrose solution. The freezing point depression constant for water is 1.86 degrees C/molal. 4.8 °C 1.4 °C -1.4 °C -4.8 °C <----?

    A solution containing one mole of glucose (C6H12O6) and a separate solution containing one mole of sucrose (C12H22O11), are each dissolved in one kilogram of water. Both solutions exhibit the same colligative properties. How is this possible? Each solution has the same number of relative particles of solute per kilogram of solvent. Each solute has a comparable molecular mass. Each solute has the same relative molecular structure. <----? Each solute has the same solubility in water.

    colligative properties depend on the ## of solute molecules, not their identities
