Question

instructions: fill in the table below with the appropriate intermolecular force. note that you are not able to type directly in the table. therefore, please enter your response in the text area below the question. what is the strongest solute - solvent interaction present when each of the following solutes dissolves in water.

	1	2	3	4
type of solute - solvent intermolecular force

Explanation:

Step1: Analyze FeCl₃

FeCl₃ is an ionic compound. When it dissolves in water, ion - dipole interactions occur between the ions (Fe³⁺ and Cl⁻) and the polar water molecules. Ion - dipole interactions are relatively strong.

Step2: Analyze Iodine (I₂)

I₂ is a non - polar molecule. In water, the main interaction is the weak London dispersion forces between the non - polar I₂ molecules and the polar water molecules.

Step3: Analyze HOCH₂CH₂OH

HOCH₂CH₂OH is a polar molecule with hydrogen - bonding capabilities due to the presence of hydroxyl (-OH) groups. Hydrogen bonding is a relatively strong intermolecular force. When it dissolves in water, hydrogen bonds can form between the HOCH₂CH₂OH molecules and water molecules.

Step4: Analyze PH₃

PH₃ is a polar molecule. The main interaction with water is dipole - dipole interaction between the polar PH₃ molecules and the polar water molecules. Dipole - dipole interactions are weaker than ion - dipole and hydrogen - bonding interactions in this context.

Answer:

1. Ion - dipole
2. London dispersion forces
3. Hydrogen bonding
4. Dipole - dipole
