What intermolecular force predominates for each substance?
A) ammonia (NH3)
B) helium (He)
C) octane (C8H18)
D) magnesium chloride (MgCl2)
E) acetonitrile (CH3CN)
Homework Answers
A)
NH3 is polar and can form intermolecular hydrogen bond , hence predominant intermolecular force is hydrogen bond.
B) He is nonpolar, hence only predominant force is London dispersion force.
C) Octane is nonpolar. hence only predominant intermolecular force is London dispersion force.
D) MgCl2 is ionic compound . So predominant force is electrostatic intermolecular force.
E) CH3CN is polar , but unable to hydrogen bond as hydrogen is attached to carbon not with nitrogen atom. hence predominant force is dipole-dipole force.

A solution contains 48.5 g of heptane (C7H16)(C7H16) and 44.0g of octane (C8H18)(C8H18) at 25∘C The vapor pressures of pure heptane and pure octane at 25 ∘C are 45.8 torr t o r r and 10.9 torr t o r r , respectively. Assuming ideal behavior, calculate each of the following. (Note that the mole fraction of an individual gas component in an ideal gas mixture can be expressed in terms of the component's partial pressure.) a)The vapor pressure of...

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...
