Bonding
The attractive force between two molecules
What is intermolecular force?
The ability for the electrons to instantaneously become non-symmetrical
What is polarizability?
Polar molecules are said to have a _________ because their atoms have very different electronegativities. Unlike temporary dipoles, they are always present.
What is a permanent Dipole?
The ability to attract electrons
What is Electronegativity?
The temperature at which enough energy is put in to break the intermolecular forces of a liquid
What is the Bioling point?
They connect different atoms to form 1 molecule
What are intramolecular bonds?
When a larger molecule creates a larger temporary dipole and therefore has a stronger dispersion force than a smaller molecule with less electrons
London dispersion forces, or LDF’s?
This bond occurs when a highly electronegative atom (an atom on the northeast side of the periodic table) is attracted to a Hydrogen in a bond with a very strong dipole
What are Hydrogen bonds?
When atoms with equal electronegativity bond, they form THIS type of bond
What are non-polar covalent bonds?
The ability for molecules to create pressure in gas form from a liquid.
What is Vapor pressure?
They are attractive forces between different molecules
What are intermolecular bonds?
The moment one side of the molecule becomes slightly negative and the other becomes slightly positive
What is a temporary dipole?
Two polar molecules attract themselves in a way that the positive end of one molecule orients to the negative end of the other
What is a Dipole?
When the electronegativities of two bonded atoms are shared unequally
What are polar covalent bonds?
The ability for a liquid to hold on to itself and support weight
What is Surface Tension?
Bonds that form between a metal (Cation) and nonmetal (anion)
What are ionic bonds?
The larger the molecule is (# of electrons goes up), the higher the chance of ________ and the higher the LDF attraction
What is polarizability?
Between the molecules, we see an intermolecular force. This force is named ______. This force can exist at the same time as dispersion forces
What are Dipol-Dipole forces?
When a large difference in electronegativity results in a "winner-takes-all" situation for bonding
What are ionic bonds?
A resistance to flow
What is Viscosity?
Bonds formed between all non-metals
What are Covalent bonds?
They are the weakest intermolecular force responsible for the attractive forces. In non-polar molecules, this is the only attractive force that exists
What are LDFs?
Hydrogen bonding can only occur with these bonds
What are O-H N-H F-H bonds?
This word can refer to the polarity of an individual polar bond, the net polarity of a polar molecule, or the polar molecule itself
What is a Dipole?
The ability of two substances to mix
What is Solubility?
