Intermolecular forces in alkanes and alkenes
Intermolecular forces in alkanes and alkenes
Weak dispersion forces (van der Waals forces)
Effect of increasing carbon chain on BP and MP
Effect of increasing carbon chain on BP and MP
Both increase due to stronger dispersion forces
BP comparison: straight-chain vs branched alkanes
BP comparison: straight-chain vs branched alkanes
Straight-chain higher (closer fit, stronger forces)
Why haloalkanes have higher BP than similar alkanes
Why haloalkanes have higher BP than similar alkanes
Polar bonds create dipole-dipole attractions
Definition of viscosity
Definition of viscosity
Liquid's resistance to pouring or flowing
Strongest type of intermolecular force
Strongest type of intermolecular force
Hydrogen bonding
Homologous series that form hydrogen bonds

Alcohols, carboxylic acids, amines, amides
Special feature of carboxylic acids affecting BP
Special feature of carboxylic acids affecting BP
Form dimers (two molecules joined by H-bonds)
Intermolecular forces in aldehydes, ketones, esters
Intermolecular forces in aldehydes, ketones, esters
Dipole-dipole attractions (no H-bonds between them)
BP ranking: alcohols, aldehydes, ketones, esters, alkanes
BP ranking: alcohols, aldehydes, ketones, esters, alkanes
Alcohols > Aldehydes ≈ Ketones > Esters > Alkanes
