Mention 3 types of intermolecular forces that exist in pure substances and which intermolecular forces are manifiested in non-polar substances?
- Sodium chloride is soluble in water, which is the most important solvent solute interaction?
Solution
The 3 types of intermolecular forces that exist in pure substances can be
(i) Ionic forces (ii) Hydrogen bonding (iii) Dipole - dipole interactions
intermolecular forces are manifiested in non-polar substances are weak vanderwaals forces, H-bonding etc
NaCl is ionic solute while water is polar solvent, the positive Na + particles are attracted to OH - ions in water
while negative Cl - particles are attracted to H + ions in water. This is how the strong H-bonding between the polar water molecules is broken.
