Dipole Dipole

organic compounds with dipole dipole forces are most soluble

polar solvents

the positive ends and the negative ends of the moleucles interact with each other

they are highly soluble in water. (water is a polar solvent)

polar molecules. when the positive end of one polar molecule interacts with the negative end of another polar molecule

higher boiling/melting point then london dispersion forces but lower then hydrogen bonds (Langdon, n.d., p. 2.4)

interactions between dipoles on neighbouring molecules

London Dispersion forces

olive oil

Subtopic

poorly soluble in water

difficult to overcome the hydrogen bonds in water molecules

low boiling/melting point (Reusch, 2020, p. 2.11)

weakest forces

the instantaneous forces are formed through random motion of electrons

organic compounds with only london dispersion forces are most soluble in

occurs between all molescules

Hydrogen bonds

non-polar solvents

highly soluble in water (Langdon, n.d., p. 2.4)

high boiling/melting point (Reusch, 2020, p. 2.11)

when reacting with a highly electronegative atom ( between H and F, N, or O) via polar covalent bond

strongest forces

Intermolecular forces

into 3 types

lipids

hydrogen bonds

semi-fluid at rtp

phospholipids

unsaturated fats

vegtable oil

weaker London dispersion forces

liquid at rtp

saturated fats

stronger london dispersion forces (Molecular Shape and Functionality, n.d., p. 5)

solid at rtp
