Question

Question: what type of intermolecular forces give rise to hydration shells in an aqueous solution of sodium chloride.

Short answer

Answer

Ion dipole interactions give rise to hydration shells in an aqueous solution of sodium chloride.

Step-by-step solution

Formation of shell 

The act of surrounding solute particles with water molecules that are organized in a particular way is known as hydration.

When a crystal of sodium chloride is dissolved in water, ions which are positively charged such as sodium ions attract the oxygen end of water and negatively charged chloride ions attract the hydrogen end of water molecules. So, individual ions gets surrounded by solvent(water) molecules by a process called solvation.

Types of intermolecular forces:

Ion dipole interactions- when an ionic compound is mixed with a polar compound these types of interactions are formed. So, during solvation of sodium chloride ion-dipole interactions are there which binds sodium/chloride ion to the water molecules and bind the first hydration shell. Additional shells are created by hydrogen bonds.
