○ hydrogen bonding
○ dipole - dipole interactions
○ dispersion forces
○ ion - dipole interactions

identify the principal type of solute - solvent interaction in a solution of nacl in c₂h₅oh
○ ion - dipole interactions
○ dipole - dipole interactions
○ dispersion forces
○ hydrogen bonding

Explanation:

1. For $Cl_2$ in $C_6H_{14}$: Both $Cl_2$ and $C_6H_{14}$ are non - polar molecules. Non - polar molecules interact through dispersion forces.
2. For $NaCl$ in $C_2H_5OH$: $NaCl$ is an ionic compound that dissociates into ions ($Na^+$ and $Cl^-$) in solution. Ethanol ($C_2H_5OH$) is a polar molecule. The interaction between ions and polar molecules is ion - dipole interaction.

Answer:

1. C. dispersion forces
2. A. ion - dipole interactions
