Q

State the trends in boiling point of organic compounds within a homologous series

A

Increase in chain length, increases boiling point
Increase in MM, increases boiling point
Straight chain > Branched chain (due to increased packing)

Q

State the trends in boiling point within the alcohol homologous series

A

16
Q

State the overall trend in viscosity

A

Viscosity increase as forces of attraction between molecules increase (as chain length increases, so too does strength of dispersion forces and thus, viscosity)

17
Q

State the overall trend in flashpoint

A

Flashpoint increases as carbon chain length increases

18
Q

State the overall trend in solubility of aldehydes/ketones/esters/alcohols/amides/amines in non-polar organic solvents

A

Solubility increases as chain length increases

19
Q

State the overall trend in solubility of alkenes/alkanes/alkynes in non-polar solvents

A

Soluble in non-polar solvents

20
Q

State the overall trend in solubility of aldehydes/ketones/esters/alcohols/amides/amines in polar solvents

A

Solubility decreases as chain length increases

21
Q

State the overall trend in solubility of alkenes/alkanes/alkynes in polar solvents

A

Insoluble in polar solvents
