Dipole Dipole
Are intermolecular forces in between or within molecules?
The forces between molecules
Which of the following does not form hydrogen bonds?
H2S
H2O
NH3
HF
H2S
True or false: London dispersion forces is a very weak attraction.
True
The intermolecular force responsible for the attraction between a polar molecule that induces a charge on a non-polar molecule
What is dipole-dipole?
True or false: Dipole-dipole interaction is the force between two molecules that each possess a permanent dipole.
True
Is this statement correct or false?
Hydrogen bonding is responsible for the relatively low boiling point of water.
This statement is false. Hydrogen bonding is responsible for the relatively high boiling point of water.
True or false: IMF strength decreases with the mass of the compound.
False. The IMF strength increases with the mass of the compound.
The intermolecular force responsible for the attraction between an ion and a polar molecule
What is ion-dipole?
What are the three types of intermolecular forces in order from strongest to weakest.
Hydrogen bonding>dipole-dipole>london dispersion
Why are methanol, ethanol, ammonia, and methylamine soluble in water?
They can form hydrogen bonds
Which is stronger F₂ or Cl₂ and why?
Cl2 is stronger because it has more electrons so there is more possibility of creating an uneven shift of electrons
If you have strong intermolecular forces, you will have _____ surface tension and _____ vapor pressure.
high surface tension and lower vapor pressure
What is the strongest force in HCl?
Dipole-dipole
What atoms does hydrogen interact with to create Hydrogen-Bond Intermolecular Forces?
Oxygen, nitrogen, and fluorine
CCl4 has a higher boiling point than HCl. Why does this happen?
This is due to the strong london dispersion forces in CCl4
If BA₂ has a electronegativity difference of .4, CD₂ has a difference of 0, and EF₂ has a difference of .2, list the molecular from highest to lowest dispersion forces:
BA₂, EF₂, CD₂
What is the strongest force in CO2?
London dispersion forces
Which IMF would have the lowest vapor pressure? Dipole-dipole or hydrogen bonding?
Hydrogen bonding
Does n-butane or n-isobutane have a higher boiling point? And why?
The boiling point of n-butane is higher than n-isobutane because it has greater London Dispersion forces.
Why is the boiling point in CH4 much lower than that of HF?
The boiling point is much lower in CH4 than that of HF because HF has hydrogen bonding
