Inorganic and Materials Chemistry

Course Code: CHEM 2330
Faculty: Science & Technology
Department: Chemistry
Credits: 5.0
Semester: 15
Learning Format: Lecture, Lab
Typically Offered: TBD. Contact Department Chair for more info.
course overview

This course investigates the structure, bonding and reactions of inorganic compounds and materials. Since the d-block metals are different from the s-block and p-block materials in their colour and magnetic properties, different theories, such as crystal field theory and molecular orbital theory, are required to understand these compounds. The bonding in ionic compounds, metals and semiconductors is studied as is the fabrication of integrated circuits, photovoltaic cells and LEDs. The laboratory stresses synthesis and instrumental methods in inorganic chemistry.

Course Content

Review

Line spectra, atomic orbitals, orbital shapes, electronic configurations, penetration and shielding. Lewis structures, valence bond theory, octet rule, dipole moment, VSEPR, molecular orbital theory, homo- and heteronuclear diatomics and s-p mixing.

Symmetry and Spectroscopy

Symmetry operations, point groups, character tables, IR spectroscopy, selection rules and chiral molecules. Proton and multinuclear NMR spectroscopy.

MO Theory: Ligand Group Orbital Approach

MO theory and the ligand group orbital approach applied to linear and bent triatomics as well as polyatomic molecules.

Introduction to Coordination Complexes

Properties of the d block metals, oxidation state, dn configuration, ligands, nomenclature, electroneutrality, coordination numbers 2-10, Kepert model of geometry, structural isomers, stereoisomers, enantiomers and diastereomers.

Bonding in Coordination Complexes

Defects in lattices, electrical conductivity in ionic solids, colour pigments and chemical vapour deposition to form silicon for semiconductors.

Materials

Methods of Instruction

The course will be presented using lectures, classroom demonstrations, problem sessions and class discussions. Audio-visual materials will be used where appropriate. The laboratory course will be used to illustrate the practical aspects of the course material. Close coordination will be maintained between laboratory and classroom work whenever possible. 

Means of Assessment

Lecture Material 70%

  • Two or three in-class tests will be given during the semester (30%)
  • A final exam covering the entire semester’s work will be given during the final examination period (30%)
  • Any or all of the following evaluations, at the discretion of the instructor: problem assignments, quizzes, class participation [5% maximum] (10% in total)

Laboratory 30%

  • Each experiment will be evaluated. The majority of the experiments will have a formal written lab report and up to two of the experiments may be evaluated by students submitting a brief report of their results followed by an oral interview. 

Note:

A student who misses three or more laboratory experiments will earn a maximum P grade.

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

Learning Outcomes

  1. Draw orbitals given a set of quantum numbers.
  2. Predict the relative magnitude of atomic radii, electronegativity and effective nuclear charge for a pair or series of elements.
