Course description
This course focuses on structure and bonding in molecules. Topics include stoichiometry review, treatment of experimental data, atomic structure, quantum theory, molecular structure, theories of bonding, kinetics, organic chemistry including nomenclature, conformation of alkanes and substitution reactions. A practical laboratory component is a required part of the course.

Learning outcomes

Upon successful completion of the course, students will be able to:

  • carry out measurements and calculations using the correct number of significant figures;
  • solve stoichiometry problems of the following types: gram-gram, solution stoichiometry, limiting reactant, and two sequential reactions;
  • explain the Bohr theory of atomic structure;
  • calculate the energy and/or wavelength of electronic transitions in one-electron atoms and ions;
  • give the electronic configuration of common elements in the periodic table;
  • predict the relative sizes, ionization energies, and electron affinities of the elements using the periodic table;
  • use electronegativity to predict dipole moment and percent ionic character in bonds;
  • draw Lewis structures for a given molecule including resonance structures and expanded valence shells;
  • use VSEPR theory to predict the geometry of polyatomic molecule;
  • use valence bond theory to describe the types of bonds in a polyatomic molecule and the hybridization of central atoms;
  • use valence bond theory to draw diagrams showing orbital overlap and geometry;
  • use molecular orbital theory to describe the bonding in any diatomic molecule involving atoms from the first row of the periodic table, or homonuclear diatomic molecules involving atoms from the second row of the periodic table;
  • use the structures of two molecules to identify the intermolecular forces that apply to each molecule, and predict which will have the higher boiling point;

  • rank the relative stabilities of carbocations;
  • name and describe the use of common laboratory equipment;
  • accurately perform standard laboratory techniques using accepted methods, such as titration, weighing, pipetting and synthesis;
  • write a report based on observations and data obtained in the laboratory;
  • apply the appropriate mathematical techniques (e.g. graphical analysis, solution of equations, etc.) to experimental data to solve for physical constants, percent yield, or related quantities;
  • determine the relationship between experimental variables using data obtained in the laboratory;
  • analyze laboratory experiments with respect to errors inherent in the method or techniques;
Means of assessment

Assessment will be in accordance with the Douglas College Evaluation Policy. The instructor will present a written course outline with specific evaluation criteria at the beginning of the semester. Evaluation will be based on the following:

  • Tests (minimum of 2): 20-30% 
  • Homework and/or in-class activities: 20-30% 
  • Laboratory: 20%
  • Final exam: 30%

Notes:

A student who misses three or more laboratory experiments will earn a maximum of a D grade. If a student arrives late, impaired, unsafely attired or otherwise unprepared, they may be subject to a mark penalty and/or may not be allowed to perform the experiment at the discretion of the instructor. If a student is not permitted to perform the experiment, this absence considered a missed lab.


A student who achieves less than 50% in either the lecture or the laboratory portion of the course will earn a maximum of a D grade.
