1. BrF has intermolecular forces of Dipole-Dipole.
because of high electronegativity difference.
Cl2 has intermolecular forces of London force
Because of no electronegativity difference.
H2S has intermolecular forces of Dipole-Dipole.
2.In the liquid state,disruptive forces are roughly of the same magnitude as cohesive forces.
3. ClBr will have larger boiling point than ClF due to high molecular weight.
4. H2O have larger boiling point than NH3 because H2O have strong Hydrogen bond and more Electronegativity difference than NH3.
5. I2 have larger boiling point than O2 because of higher molecular weight.
6.False
In gaseous state disruptive forces are more than cohesive forces.
7.volatile liquid are those liquid which evaporates easily at room temperature eg: Gasoline
8.False
change of state from gas to solid is called deposition and the process is exothermic.
9.More the intermolecular forces it will tougher for a molecule to escape so higher temperature is required to boil.
so more intermolecular forces more boiling point.

2. Identify the strongest type of intermolecular forces in acetone, ethanol, water and hexane. (Structures listed on page 15.) Experiment 2 Intermolecular Forces There are three general types of intermolecular forces. All substances exhibit London Dispersion Forces (LDF), and they are generally the weakest of the three types. These London forces are due to the attractions between small, temporary dipoles that arise from the constant, random movement of the electrons in a substance. As molar mass increases, the size of...

h of the following statements is NOT true? London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...
