IB Chemistry Topic 4.4: Polarity, Intermolecular Forces & Solubility

To watch this entire video, head over to our website (link below) and register for access today!

This video covers IB Chemistry subtopic 4.4 from the IB Chemistry topic 4 syllabus content.

This video starts by reviewing the concept of electronegativity and how this affects the polarity of a bond, with examples. It then discusses how the overall molecular shape and bond distribution affects the polarity of a molecule. This is followed by the introduction of intermolecular forces, including London dispersion forces, dipole-dipole forces, and hydrogen bonds, and comparison of their properties. The video concludes by explaining how molecular solubility is related to intermolecular forces and these impact the solubility of an alcohol chain.
