will dissolve in the methanol because of similar intermolecular attractions.

will dissolve in the methanol because their molar masses are so close.

will dissolve in the methanol because both molecules are polar.

will not dissolve in the methanol because one molecule exhibits hydrogen bonding and the other does not.

will not dissolve in the methanol because their molar masses are so close.

Solutions

Expert Solution

The general dissolving rule is like dissolves like. It means polar solute dissolves in polar solvents and non-polar solute dissolves in non-polar solvents.

Example: methanol is polar and water is polar hence, mehanol dissolves in water.

Ethane(CH3CH3) is a non-polar molecule.

Methanol is a polar molecule and exhibits hydrogen bonding due to presence of -OH bond.

Ethane and methanol both have different intermolecular forces.

Thus, ethane gas will not dissolve in the methanol because methanol exhibits hydrogen bonding and ethane does not.

Hence, ethane gas will not dissolve in the methanol because one molecule exhibits hydrogen bonding and other does not.

Consider the evaporation of methanol at 25.0 ?C : CH3OH(l)?CH3OH(g) . Why methanol spontaneously evaporates in open air at 25.0 ?C : Methanol evaporates at room temperature because there is an equilibrium between the liquid and the gas phases. The vapor pressure is moderate (143 mmHg at 25.0 degrees centigrade), so a moderate amount of methanol can remain in the gas phase, which is consistent with the free energy values. A.) Find ?G? at 25.0 ?C . B.) Find ?G...
