AP chem - chapter 11 (in textbook) IMFs

intermolecular forces

forces of attraction between (at least 2) molecules, which influence the physical properties of substances, including boiling points, melting points, and solubility.

solids have __ IMFs than liquids

stronger

4 IMFs

dipole-dipole (perm polar molecules/dipole moments), hydrogen bonding, LDFs, and ion-diople forces

because solids have stronger IMFs, they have ___ shape and volume

definite

liquids are held together by medium-ish strength IMFs, that’s why they have __ volume and __ shape of their container

definite, assume

molecular compounds of low molecular weight tend to be __ at room temp

gases

LiCl is a ionic __ at room temp

solid
