1.
List all of the different intermolecular interactions (IMFs) that are possible in a solution of CaCl
2 in methanol (CH 3 OH). Explain how/why these are possible
Solution
Answer: CaCl 2 has inonic bond within the molecule.
Methanol (CH 3 OH) has hydrogen bonding between another molecule while within the molecule
it has covalent linkage.
When CaCl 2 in dissolved in methanol the solubility is due to formation of ion-dipole forces.
This is due to fact that this force develops because of the interaction of ions and polar
molecule.
The slightly negative Oxygen of methanol is attarcted towards Ca 2+
while slightly positive
Hydrogen gets attracted to Cl -
