FSc Chemistry Book2, CH 7, LEC 18 sp Hybridization and Pi Orbitals

This video lecture from Fundamental Principles of Organic Chemistry (F.Sc. second year Chemistry) covers sp mode of hybridization and the formation of two pi bonds by the un-hybridized orbitals perpendicular to each other. Alkynes show sp hybridization where one s and a p orbital hybridizes to form two degenerate sp orbitals in a linear geometry. Two pi bonds with perpendicular overlapping are formed as a result. A summary of all hybridization types and corresponding geometries is presented at the end.
