Classify the strongest type of intermolecular force in the follow- ing interactions: solvent–solvent, solvent–solute, and solute– solute when solid iodine 1I22 is placed in the water. Based on these interactions, predict whether I2 is soluble in water.

Hello everyone today. We have the following problem A student mixed ethanol, the solute and water. The solvent together identify the inter molecular force present between solvent solvent solvent solute and salute, salute, predict whether ethanol is miss a bubble in water. So first we have to recall the formulas for both ethanol and water. So ethanol is going to have a method, a methylene group and a hydroxy group and water. It's simply a church too. Oh now what's important or special about these two groups is that they both have this O. H. Group present and when you have an O. H. Group present you have what's known as hydrogen bonding. So if we look at the different relationships for example the solvent solvent this is essentially how water interacts with water. This is going to have hydrogen bonding. And then if we look at the solvent salyut interactions which is the water and the ethanol, they both have that O. H. Group and can therefore engage in hydrogen bonding. And lastly if we look at the salyut solid interactions which is between the ethanol interacting with the ethanol. We note that this also is going to have hydrogen bonding. And so since the solvent solute interactions here have hydrogen bonding we can say that ethanol is admissible in water admissible. Just means that it's able to be dissolved in. So ethanol is admissible in water and then we have the following interactions here which will constitute hydrogen bonding overall. I hope this helped and until next time
