Homework Answers
Ans : b) the forces of attraction between water - water and acetone - acetone are very strong, while the forces of attraction between water-acetone are relatively weak.
Water molecules exhibit hydrogen bonding in between their molecules due to which it has a high boiling point. Acetone is a permanent dipole so it has dipole-dipole interactions in between its particles which are comparatively weaker than the attraction forces in water. This is the reason acetone evaporates faster.

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...

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...

Intermolecular forces (IMPs) are the forces of attraction (or sometimes repulsion) that act between neighboring molecules All IMPs are based on etectrostatic interaction and are relatively weak compared to the Intramolecular forces that hold the atoms within a molecular together. In today, workshop you will practice to identify IMFs and predict their effect on boiling point melting point, vapor pressure and enthalpy of vaporisation (Delta Hvap). The Delta Hvap for a given molecule is the energy required to transform a...

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...
