Chemical Bonding and Shapes of Molecules - Chemistry (Undergraduate Foundation)
Chemical Bonding and Shapes of Molecules - Chemistry (Undergraduate Foundation)
This course covers the principles that govern how atoms connect to form molecules. It provides a full treatment of ionic and covalent bonding, valence forces, and the various types of intermolecular forces, including hydrogen bonding. The core of the course is a practical guide to predicting the three-dimensional shape of molecules using VSEPR theory and the concept of orbital hybridization. A command of chemical bonding and molecular geometry is essential for understanding the properties and reactivity of all chemical substances. The shape of a molecule dictates its function, from the specificity of drug-receptor interactions in medicine to the properties of polymers in materials science. This is the foundational knowledge for designing new molecules and materials. By the end of this course, you will be able to draw Lewis structures for any molecule, predict its three-dimensional geometry and bond angles using VSEPR theory, and determine its polarity. You will also be able to explain the formation of sigma and pi bonds using the concept of orbital hybridization and identify the types of intermolecular forces present in a substance. This course is for students who have a complete understanding of atomic theory and electronic configuration. It is a mandatory course for all students of chemistry, biochemistry, and materials science, and a direct prerequisite for the study of organic chemistry.

[NUC Core] CHM 101: General Chemistry I
This learning track delivers the complete NUC CCMAS curriculum for General Chemistry I. It is a comprehensive programme designed to build a robust, university-level foundation in modern chemistry. The track systematically covers all essential topics, from atomic theory, chemical bonding, and the states of matter, to the quantitative principles of stoichiometry, equilibrium, thermodynamics, and kinetics. This programme is for first-year undergraduates in science, technology, engineering, and mathematics (STEM) faculties who are required to take CHM 101. It is also essential for any student or professional globally who needs a rigorous and complete foundation in first-year university chemistry for further study or career development. This track delivers a full skill set in chemical theory and quantitative problem-solving. Graduates will be able to determine molecular structures, calculate reaction quantities, analyse the energetics and rates of reactions, and solve complex equilibrium problems. This programme provides the non-negotiable prerequisite knowledge for all subsequent chemistry courses and for any degree in the physical sciences, engineering, or medicine.
