Consider the ions and molecules in model 1
WebJul 1, 2024 · When ionic compounds dissolve in water, the ions in the solid separate and disperse uniformly throughout the solution because water molecules surround and solvate the ions, reducing the strong electrostatic forces between them. This process represents a physical change known as dissociation. WebPart 1: Rank the following in order of increasing strength of their respective intermolecular forces. Weakest IMF Lowest to Highest BP 1. Ketone= Upside down looking 2. Ether 3. Alcohol Strongest IMF The following questions compare properties of molecules represented by space-filling models.
