Q11. This question is about water. Water is a polar covalent molecule. The strongest intermolecular forces between water molecules are hydrogen bonds. (i) The O–H bond in water is polar because, when compared with the hydrogen atom, the oxygen atom has. a higher mass number. a larger atomic radius.Example 6.3.1: Sugar and Water. A solution is made by dissolving 1.00 g of sucrose ( C 12H 22O 11) in 100.0 g of liquid water. Identify the solvent and solute in the resulting solution. Solution. Either by mass or by moles, the obvious minor component is sucrose, so it is the solute. Water —the majority component—is the solvent.To transition between phases intermolecular forces must be formed or broken. A boiling point is the transition between a liquid state and a gaseous state which requires the breaking of intermolecular forces. Breaking intermolecular forces requires energy (heat) and the amount of energy is determined by the intermolecular forces themselves.S13.5. There are 3 types of intermolecular force: London Dispersion, Dipole-Dipole (Example: Two \ (NaCl\)) and Ion-Dipole (Example: \ (Mg^+\) and \ (HCl\)) Dipole- Dipole occurs between polar molecules. Ion- Dipole occurs between an ion and polar molecules. London Dispersion occurs between the nonpolar molecules.At a sufficiently low temperature, a liquid does not have enough kinetic energy to overcome intermolecular attractions, and changes into: solid. Intermolecular forces occur: between separate molecules. Matter that is super-ionized such that it is no longer strictly atomic is a: plasma. The image below was captured over a hot mug of coffee on a ...Intra molecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms.
