Intramolecular Bonds
Intramolecular bond between two metals
Metallic bond
Intermolecular bond between hydrogen and either nitrogen, sulfur, or oxygen
Hydrogen bond
The difference between a polar molecule and a nonpolar molecule.
In a polar molecule, one side has a partial positive charge and the other side has a partial negative charge.
In a nonpolar molecule, neither side has a partial charge.
The difference between C – C and C = C
The – symbol represents a single bond (2 shared electrons), while the = symbol represents a double bond (4 shared electrons).

Ionic bond
True or false? The bond between H and O within a molecule of H2O is called a hydrogen bond.
Use an electronegativity table to determine if carbon monoxide is polar or nonpolar.
If the difference in electronegativity is. . .
< 0.4 it's nonpolar covalent
≥ 0.4 and ≤ 1.7 it's polar covalent
> 1.7 it's ionic
Polar
The difference in electronegativity between carbon and oxygen is 1.0

Covalent bond
The reason why dipole-dipole bonds are stronger than bonds caused by London disperson forces.
A dipole is when one side of an atom has a partial positive or negative charge. The dipoles in London disperson are temporary, due to random electron movement); the dipoles in dipole-dipole bonds are permanent, due to differences in electronegativity.
What electronegativity is and how it connects to polarity.
Electronegativity is how strongly an atom attracts shared electrons in a compound. If two elements with a significant difference in their electronegativities bond, the electron is shared unevenly. This causes one side to have a partial positive charge and the other side to have a partial negative charge (aka polarity).
The reason why oxygen must be the central atom in a water molecule
Hydrogen needs only 2 valence electrons to become stable. If hydrogen is in the center, it would be bonded to two other atoms, meaning that it would share 4 4 electrons. This is too many.

The difference between an intramolecular and an intermolecular bond
Intramolecular bonds occur within a molecule (for example, the bond between H and O in H2O).
Intermolecular bonds occur between molecules (for example, a bond between two water molecules).

Attraction between two polar molecules, where the negative side of one molecule is attracted to the positive side of another
The reason why a stream of water bends toward a ballon rubbed with static electricity.
Water is a polar molecular. The hydrogens, which have a partial positive charge, are attracted to the electrons on the balloons. (Opposite charges attract.)

Definition of London disperson forces
When random electron movements cause an atom to have a positively-charged and negatively-charged side, that atom is electrically attracted, temporarily, to its neighbors. (Opposite charges attract.)
The reason why olive oil and vinegar (acetic acid) don't mix.
Polar molecules only dissolve other polar molecules. Nonpolar molecules only dissolve other nonpolar molecules. (In other words, "like dissolves like".) Vinegar is polar; olive oil is nonpolar.
