CHEM 121 (CHEM121)

Struggling to keep up with CHEM 121? This ultimate Semester 1 study guide breaks down everything you need to ace your first university chemistry course – without drowning in textbooks. What’s inside: Atomic Structure to Quantum Mechanics – explained clearly for fast understanding Bonding, Shapes, Polarity & Orbitals – with diagrams & step-by-step examples MO Theory vs. VBT – so you finally know which one to use and when Intermolecular Forces, Periodic Trends, Thermo, Light...

This chapter goes in depth about intermolecular forces (Van der Waals forces). In relates melting points, boiling points, atomic radius and charge to the strength of the forces.

Introduction to Organic Chemistry

This chapter discusses colors and conjugate systems. This includes knowledge of pi bonds, molecular orbitals, atomic orbitals and electromagnetic spetrum

This chapter shows how hybrid orbitals look like, energy of hybrid orbitals, how to sketch Valence Bond Diagrams and Orbital Overlap Diagrams

This chapter relates back to chapter 2 (lewis structures) and Chapter 7 (electronic configuration). We study how some molecules are able to have double bonds and why some can’t create double bonds.

This chapter focuses on multi-electron theory instead of just one. We see how z effective effects where the position of an electron is located and thus the size of the atom.

In relation to the previous chapters, we now look at how electrons move between shells and how energy changes (emission or absorption)

This chapter goes into depth about each orbital characteristic. S,P,D and F…

Chapter 4 discusses about Quantum theory…Quantum numbers such as principles numbers, spin numbers, angular momentum numbers and etc…
