The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules.
Thank you ?

Describe the difference between intra- and intermolecular forces, distinguish the different types of forces among molecules,...
20. Intermolecular forces exist between molecules. Describe the intermolecular forces that exist in the following examples: a) water (describe how many (at least 2) water molecules would interact) b) hexane (describe how many (at least 2) hexane molecules would interact) c) acetone (describe how many acetone ( at least 2) molecules would interact)
NH3, has the same molecular shape as PCl3. Which intermolecular forces are present between NH3 molecules? How are they different than the forces between PCl3 molecules?
select all types of intermolecular forces found between the following pair of molecules: HI and HCl Select all types of intermolecular forces found between the following pairs of molecules: HI HCL and A) Hydrogen Bonding B) lon - Dipole forces C) London Dispersion forces D) Dipole - Dipole forces
Explain how intra/intermolecular forces within polymers and between polymer chains affect the shape of the polymer.
Chemistry 2 help with lab questions! Intermolecular forces are not chemical bonds. Explain the difference. When answering the rest of the essay questions, use language that clearly distinguishes between chemical bonds and intermolecular forces. Why do compounds with higher intermolecular forces have higher boiling points? Show that you understand why a higher temperature is needed to boil a compound that has stronger intermolecular forces. Which has greater dispersion forces, hexane or pentane? How can you use their molecular formulas to...
We discussed the different types of intermolecular forces in this lesson, one of which was the hydrogen bond. Which of the molecules below would have this type of intermolecular force? A. HCl B. all of the above C. H2 D. CH4 E. CH3CH2OH
1.) What kind of intermolecular forces exist between molecules of Br2? A) Dispersion B) Dipole-dipole C) Hydrogen bonding D) Ion-dipole bonding E) A and B F) A, B, and C 2.) If considering a random molecule, how does molecular weight influence vapor pressure? A.)higher molecular weight = doesn’t impact vapor pressure B.)higher molecular weight = lower vapor pressure C.)higher molecular weight = we need more information to determine how this impacts vapor pressure D.)higher molecular weight = higher vapor pressure
1. Describe and compare the motion and interactions of molecules in the three different phases of matter 2. Explain the relationship between temperature and intermolecular forces as it affects the phase of matter. 3. List the steps necessary to determine the intermolecular forces present in a pure substance.
Define intermolecular forces and explain the type of intermolecular forces present between alcohols, phenol and thiol molecules. Citing would be very helpful.
INTERMOLECULAR FORCES INTRODUCTION LEARNING OBJECTIVES To relate the effecet of intermolecular forces on relative melting points and vapour pressures of some organic substances THEORY Weak attractive forces that occur between individual molecules in substances are called intermolecular forces. These include London dispersion forces, dipole-dipole forces and hydrogen-bonding forces. Collectively, the three types of intermolecular forces are referred to as Van der Waals forces. These attractive forces are much weaker than the chemical bonds between atoms in a molecule. Note that...
