Question
Chapter 4, Problem 4.60AP
(a)
Interpretation Introduction
Interpretation:
The compound, which exhibits weaker intermolecular forces, has to be given.
Concept introduction:
London Dispersion forces:
London dispersion forces are weak interactions due to the temporary changes in electron density in a molecule. All covalent compound exhibits London dispersion forces. These intermolecular forces are the only intermolecular forces present in nonpolar compounds.
Hydrogen Bonding:
A
Dipole-dipole interactions:
Dipole–dipole interactions are electrostatic interactions between molecules which have permanent dipoles. This interaction is stronger than the London forces but is weaker than ion-ion interaction because only partial charges are involved positive end of a polar molecule will attract the negative end of the other molecule and influence its position
(b)
Interpretation Introduction
Interpretation:
The compound that has lower boiling point has to be given.
(c)
Interpretation Introduction
Interpretation:
The compound that has lower melting point has to be given.

Calculating the pH at equivalence of a titration
A chemist titrates 210.0 mL of a 0.1003 M hydrobromic acid (HBr) solution with 0.7550M KOH solution at 25 °C. Calculate the pH at equivalence.
Round your answer to 2 decimal places.
Note for advanced students: you may assume the total volume of the solution equals the initial volume plus the volume of KOH solution added.
