intramolecular forces are () bonds () a molecule holding atoms together

strong, within

intermolecular forces are () attractions () separate molecules that influence ()

weaker, between, physical properties

imf relative strength

ion-ion, ion-dipole, hydrogen bonding, dipole-dipole, dipole-induced dipole, London dispersion forces

molecular shape angles, linear, trigonal planar, tetrehedral, trigonal pyramidal, bent

180, 120, 109.5, 107, 105

bent vs pyramidal:

three bonding and at least one unbonding domain (lone pair) =

two bonding and at least one unbonding domain (lone pair) =

trigonal pyramidal, bent

ldf occur between () covalent molecules/atoms. sometimes referred to as just dispersion forces, electrons temporarily () distribute. its the weakest because () are temporary. Ldf is present in all molecules

nonpolar, unequally, dipoles

covalent bonds are formed by the () of electrons between atoms. covalent bonds occur between two () atoms

sharing, nonmetal

ionic bonds are formed by electrostatic attraction between oppositely charged () which are atoms/molecules that either gained or lost (). ionic bonds occur between one () and one () atom

ions, electrons, nonmetal, metal

boiling point: stronger imf () boiling points

increase

melting point: stronger imf leads to () melting point

higher

solubility: Non-polar solutes tend to dissolve in () solvents while polar solutes tend to dissolve in () solvents. This is known as the “() dissolves ()” rule.
