Secondary Interactions and Alkanes

Flashcards about Secondary Interactions and Alkanes

Dispersion forces

Operate in all molecular substances and increase with molecular mass due to the increased number of electrons, leading to higher boiling points.

Dipole-Dipole forces

Polar molecules have both dispersion forces and these forces, resulting in higher boiling points compared to non-polar molecules of the same mass.

Hydrogen bonding

The strongest of the secondary interactions, occurring in molecules with H-N, H-O, and H-F bonds.

Ion-dipole forces

Attraction between ions and polar molecules.
