PROBLEM \(\PageIndex{1}\)
Suggest an explanation for the observations that ethanol, C2H5OH, is completely miscible with water and that ethanethiol, C2H5SH, is soluble only to the extent of 1.5 g per 100 mL of water.
- Answer
-
The hydrogen bonds between water and C2H5OH are much stronger than the intermolecular attractions between water and C2H5SH.
PROBLEM \(\PageIndex{2}\)
Which of the following gases is expected to be most soluble in water? Explain your reasoning.
- CH4
- CCl4
- CHCl3
- Answer
-
(c) CHCl3 is expected to be most soluble in water. Of the three gases, only this one is polar and thus capable of experiencing relatively strong dipole-dipole attraction to water molecules.
