This video covers HL IB Chemistry subtopic 14.1 from the HL IB Chemistry topic 14 syllabus content.
This HL video begins by introducing the concept of formal charge to decide between possible Lewis structures, including the formula used. It then covers advanced VSEPR theory, up to six electron domains, and how these are affected by the presence of lone pairs. Finally, it covers the definition, creation, and representation of sigma and pi bonds. It explores these within varying bonds, including: single, double, and triple covalent bonds.
