Intermolecular Force Worksheet
1. Identify the strongest intermolecular force present in pure samples of the following substances:
SO2
H2O
CCl4
SCO
PCl3
SO3
2. Identify the strongest intermolecular force operating in the liquid phase of the following substances. Fully explain how you determined this.
a. Cl2
b. CO
c. SO2
d. CO2
e. HF
f. NH3
3. Based on the intermolecular forces present, rank the relative boiling points of each of the substances below. Arrange each series of substances in order of increasing boiling point. State your reasons for the order you use (identify the forces and explain how they affect the boiling point).
a. Water, methane and phosphorus trichloride
b. Br2, Cl2, I2
A strip of aluminium of mass 42.7g is dropped into a beaker of dilute hydrochloric acid. Calculate the work done (in J) on the surrounding atmosphere (1atm pressure, 24oC ) by the evolution of hydrogen in the subsequent reaction

Problem- Determine the amount of acid or base required to adjust the pH of a water sample from 11 to 8.5, given that the initial alkalinity is 80 mg/L as CaCO3.
A volume of 60.0 mL of aqueous potassium hydroxide(KOH)was titrated against a standard solution of sulfuric acid(H2SO4). What was the molarity of the KOH solution if 24.7 mL of 1.50M H2SO4 was needed? The equation is: 2KOH(aq)+H2SO4(aq)-->K2SO4(aq..
From 5g of benzopinacol you obtained benzopinacolona 75% crude. The yield after recrystallization was 2 grams. benzapinacol molecular weight = 366.46 g / mol benzopinacolone molecular weight = 348.44 g / mol determine:
Consider a solution formed by mixing 60.0 mL of 0.100 M H2SO4, 30.0 mL 0.100M HOCl, 25.0 mL 0.180M NaOH and 25.0 mL 0.100 M Ba(OH)2. Calculate the pH of this solution.
Use the Henderson-Hasselbalch equation to calculate the pH of a 250 mL solution of 0.3 M acetic acid (pKa = 4.76; assume it is initially fully protonated)
