I need help drawing these intermolecular forces with dissolving in water

Part Apply your learning and relate to intermolecular forces Der a picture in the space below of wis h the following dissolving in water. Be sure to show the facts with the dissolved p les and provide a key where c ry. Noter you will not find these compends on the simulation Need help Nead section in your textbook or read the Khan Academy article aramalaran intermolecular force MgSO, NICE Methanol CH,CO.Na H-ċ-H 9) Which of the substances that you drew particle level pictures for above will form ions when dissolved in water a. What type of intermolecular force is it when ions interact with water? b. Do you think it would be stronger or weaker than dipole-dipole intermolecular forces? When a substance is heated to its boiling point, the energy put in disrupts the intermolecular forces causing the substance to go into the gas phase (we are not breaking bonds! If we did then we would be forming hydrogen gas when we boil water and not water vapor What do you think the relationship is between intermolecular force strength and boiling point? Why do you think that

Answer 1

Dipole - Dipole force Dipole - Opole force act between the molecules possessing permanent dipole. Ends of the dipoles possess 'partial charges which results in elechostatic interaction beturen the endsey theo clopole Ideally - ALB). even distribution of electon cloud, electronegativity. AKB 3.S+ So 1 st Sest election cloud is distorted towards mere cliente negative dipole - cijele force linteraction Hydrogen Bond ih-bond) H-bond is a special case of dipole - cipele interaction. This is found in the molecules in which brightly polar H-f, O-HOL N-H bonds are present. Although hydrogen bending is regarded as being limited to fio and N, but species such as a may also present in hydrogen bonding • Necessary condition for H-bond - presence of H-F, 0-HC N-H bo chom X Moon Hibond.

lon. Gipole Interaction 1. It is the result of an electrostatic interaction between a charged in and a molecule that has a dipele. It is attractive force that is commonly found in solutions, especially ionic compound dissolveding polar solvent.

19 NHUU , Mg soy and CHELOg Na We'll farm ions when dissolved in water, while most of the CH3OH (methanol) will be present in its indissociated form. fin (a) When ions are dissolved in water , they interact with solvent (water) molecule via ion-dipole Interactions ; (b) pon-dipole Interactions are stronger than dipole-dipole Interaction as forener has complete wharge and thus able to interact with solvent molecule more strongly wa electrostatic force, while in dipole-dipole mteraction, the molecules hold partial change, the show cicak mttraction. (C) Boiling point can be understood as temperature upto which a bulk is to be heated cle.increasing the energy), so that the intermolecular athrachon lion-dipole, Hydrogen bond, dipole - dipole ett) between the molecules are broken and now molecules are able to leave the bulk. This temperature low heat supplied) is directly proportional to the strength of intermolecular force of attraction between the molecules. So, we can say that Boiling point is directly proportional to intermolecular force of attraction. More the strength lor extensive ) intermolecules attrachen, higher will be boiling poing inci
