2.4 sg Flashcards
what is the london dispersion force
weakest intermolecular force; makes atoms form temporary dipoles
What type of molecules make up london dispersion forces
Anything!!!
What are dipole-dipole interactions
A bond between a partially positive and negative molecule
what type of molecules make up dipole-dipole interactions
polar molecules
what are hydrogen bonds
strongest type of bond; happens between polar molecules (has to include hydrogen)
What type of molecules make up hydrogen bonds
Hydrogen atom + nitrogen, oxygen, or fluorine
Weakest force?
London dispersion
Mid-strength force?
Dipole-dipole interaction
Strongest force?
Hydrogen bond
How do you determine if a molecule is nonpolar?
Equal pull between molecules, equal charge
How do you determine if a molecule is polar?
Inequal pull between molecules, positive and negative charge and EN stronger on one side
Based on the structure of water, what intermolecular forces will the molecule be able to make?
London dispersion, dipole-dipole, hydrogen
Based on the structure of oil, what intermolecular forces will the molecule be able to make?
London dispersion only
Will a molecule of ethyl alcohol be hydrophobic or hydrophilic based on its structure?
Hydrophilic
Will a molecule of oil be hydrophobic or hydrophilic based on its structure?
Hydrophobic
