CHEM1903 - Resources for Week 7
Topics and Learning Outcomes
Gas Laws
use the ideal gas law to relate the number of moles, pressure, volume and temperature of a gas relate gas density and molar mass convert between the common units of pressure (atm, Pa and mmHg) use the appropriate value of the gas constant, R
Types of Intermolecular Forces
identify the main types of intermolecular forces, and explain their importance in the formation of condensed phases predict trends in the strength of intermolecular forces with, for example, charge, dipole moment and molecular weight identify the relationship between boiling point, vapour pressure, enthalpy of vapourization and the strength of intermolecular forces use intermolecular forces to explain the concept of “like dissolves like" explain the hydrogen bond, identify the elements and bonds that may undergo hydrogen bonding, and draw the structure of a hydrogen bond relate the strength of intermolecular forces to boiling points, and explain why this is a useful measure explain amphiphilicity and define amphiphiles and surfactants, and describe their key properties
Polymers and the Macromolecular Consequences of Intermolecular Forces
describe the random coil conformation of a polymer, and calculate the random coil diameter and contour length of a vinyl (addition) polymer
explain how entanglement and chain branching affects polymer properties give examples of natural addition and condensation polymers, and draw an amino acid and a peptide linkage explain primary, secondary, tertiary and quaternary structure in proteins recognise the types of intermolecular forces in natural and synthetic polymers
