Viscosity/Boiling Point/Solubility/Flashpoint Trends Flashcards
State what homologous series have the highest boiling point
Carboxylic acid/alcohols/amines/amides
State the IMF forces of carboxylic acids
Hydrogen bonding and weak dispersion forces
State the IMF forces of alcohols
Hydrogen bonding and weak dispersion forces
State the IMF forces of amines
Hydrogen bonding and weak dispersion forces
State the IMF forces of amides
Hydrogen bonding and weak dispersion forces
State the trends in boiling point of organic compounds within a homologous series
Increase in chain length, increases boiling point
Increase in MM, increases boiling point
Straight chain > Branched chain (due to increased packing)
State what homologous series have the second highest boiling point
Haloalkanes/aldehydes/ketones/esters
State the IMF forces of haloalkanes
Dipole-dipole attractions and weak dispersion forces
State the IMF forces of aldehydes
Dipole-dipole attractions and weak dispersion forces
State the IMF forces of ketones
Dipole-dipole attractions and weak dispersion forces
State the IMF forces of esters
Dipole-dipole attractions and weak dispersion forces
State what homologous series have the third highest boiling point
Alkanes
State the IMF forces of alkanes
Weak dispersion forces
State what homologous series have the fourth highest boiling point
Alkenes/alkynes
State the trends in boiling point within the alcohol homologous series
primary > secondary > tertiary
due to decreased op. for hydrogen bonding with other molecules
