NomenclatureCurrent Lecture- Interactions between molecules influence their bulk properties o These interactions are known as London Dispersion forces, Dipole Dipole forces, and Hydrogen bonding.o Alkanes only have LD forceso The greater the surface area of the molecule, the greater the LD forces and therefore higher boiling point.- Branching lowers the boiling point because there is a smaller surface area- Dipole Dipole must have polar covalent bonds. - Hydrogen bonds are stronger than other dipole dipole interactions - Electronegativities also play a part, ethanol has a higher boiling point than ethylamine does because oxygen is more electronegative than nitrogen- Nomenclature o Cyclic compounds Add prefix cyclo, name substituents, give the lowest number to the highest priority functional group These notes represent a detailed interpretation of the professor’s lecture.
