What happens to molecules when water boils?
What happens to molecules when water boils?
Molecules stay intact; only intermolecular forces break
Which intermolecular force exists in ALL molecules, both polar and non-polar?
Which intermolecular force exists in ALL molecules, both polar and non-polar?
Dispersion forces
Which order correctly ranks intermolecular forces from weakest to strongest?
Which order correctly ranks intermolecular forces from weakest to strongest?
Dispersion < Dipole-dipole < H-bonding
Why do dispersion forces increase with molecular mass?
Why do dispersion forces increase with molecular mass?
More electrons make temporary dipoles easier
Why does butane (bp ) have a higher bp than 2-methylpropane (bp )?
Why does butane (bp ) have a higher bp than 2-methylpropane (bp )?
Linear shape gives greater surface contact
Why is dipole-dipole attraction stronger than dispersion forces?
Why is dipole-dipole attraction stronger than dispersion forces?
It involves permanent not temporary dipoles
Which atoms must H be bonded to for hydrogen bonding to occur?
Which atoms must H be bonded to for hydrogen bonding to occur?
N, O, or F only
Why doesn't chlorine form hydrogen bonds despite high electronegativity?
Why doesn't chlorine form hydrogen bonds despite high electronegativity?
Cl atoms are too large
Which has the highest bp: methanol (), methanal (), or ethane ()?
Which has the highest bp: methanol (), methanal (), or ethane ()?
Methanol due to hydrogen bonding
Why does HF have the highest bp (19.5°C) among hydrogen halides despite smallest size?
Why does HF have the highest bp (19.5°C) among hydrogen halides despite smallest size?
Hydrogen bonding is stronger than other forces
