2.4- Intermolecular Forces Flashcards
Describing the different types of intermolecular attractions
London dispersion forces (LDF), dipole- dipole interactions, and hydrogen bonding
Covalent, Ionic, Hydrogen, Dipole-Dipole, and London Dispersion from strongest to weakest pull
Covalent, Ionic, Hydrogen, Dipole-Dipole, London Dispersion
What makes a molecule polar
when is is partially negative and partially positive
what elements typically bond in a hydrogen bond O-H, F-H, and N-H
O-H, F-H, and N-H
What makes an element soluble in water based off its structure:
the element must be polar
What is an element called if it is ‘water-loving’
hyrdrophilic
what is an element called if it is ‘water-hating’
hydrophobic
definition of intermolecular
existing or taking place between molecules.
what is a simple definition of a london dispersion bond
two polar molecules attracted to eachother
what is a simple definition of hydrogen bond
interaction between two molecules that each contain an O-H, F-H, or N-H
what is a simple definition of a dipole-dipole
-stronger than london
-when electrons are permanently distributed asymmetrically in a molecule resulting in permanent partial changes
-present in polar molecules only
Do polar or non-polar molecules dissolve in water?
polar molecules dissolve in water
Will non-polar molecules dissolve in water?
no
Are polar molecules hydrophilic or hydrophobic?
Polar molecules are hydrophilic
Are non-polar molecules hydrophilic or hydrophobic?
Non-polar molecules are hydrophilic
