Why do alkanes show increasing boiling points as carbon chain length increases?
Why do alkanes show increasing boiling points as carbon chain length increases?
Stronger dispersion forces & more contact
Why does butane have a higher boiling point () than methylpropane ()?
Why does butane have a higher boiling point () than methylpropane ()?
Butane is linear; fits closer together
Why do haloalkanes have higher boiling points than alkanes with similar carbon atoms?
Why do haloalkanes have higher boiling points than alkanes with similar carbon atoms?
Dipole-dipole forces plus dispersion
What happens to viscosity as hydrocarbon chain length increases?
What happens to viscosity as hydrocarbon chain length increases?
Viscosity increases

Why do carboxylic acids have particularly high boiling points?
Why do carboxylic acids have particularly high boiling points?
Form dimers held by two hydrogen bonds
Why can't aldehydes and ketones form hydrogen bonds with each other?
Why can't aldehydes and ketones form hydrogen bonds with each other?
No H atom bonded directly to O or N
Rank intermolecular forces by strength (strongest to weakest):
Rank intermolecular forces by strength (strongest to weakest):
