This results in a molecule where the center of positive charge (defined by the nuclei) does not coincide with the center of negative charge(defined by the electron orbitals).
does this mean that the positive and negative charge are equal distance apart?

The the term InterMolecular Force (IMF) literally means the forces between molecules, and as such, is often a misnomer, as simply speaking, not all matter is composed of molecules. Yet this term is used pervasively, and so we will use it, but first lets compare it to the so called "intramolecular forces", the forces within the proverbial "molecule.
This explanation is a little confusing, could you give a shorter explanation?

. Water vapor (the term vapor refers to the gaseous form of a substance that is a liquid or a solid under normal conditions so nitrogen (N2) and oxygen (O2) are referred to as gases
I am a little confused as to how water vapor is considered a liquid or gas at normal conditions

second period elements have no d orbitals and so can not have more than an octet of electrons, that is, only the third period and greater can form sp3d and sp3d2 orbitals.
How come there are no hybrid combinations with the f orbital?

Recall that a lowercase Greek delta (δδ\delta) is used to indicate that a bonded atom possesses a partial positive charge, indicated by δ+δ+\delta^+, or a partial negative charge, indicated by δ−δ−\delta^-,
why are the charges partial?

The "octet rule" says that in many compounds the most stable (correct) electron configuration is when there are 8 electrons (four filled orbitals). This is a consequence of the fact that many compounds involve the S and P block electrons, which contribute 4 orbitals and can thus contain 8 electrons.
I remember that there are exceptions to breaking the octet rule. Isn't it that elements in period 3 or below are capable of breaking it if need be?

If on the other hand, the ions are more attracted to the water, the leave the crystal and the compound is soluble.
So if the ion has a smaller charge than the water the compound is soluble?

Carbon dioxide and water are also released if the compound contains carbon.
So will water always be a product of a combustion reaction?

Compounds that consist of a nonmetal bonded to a nonmetal are commonly known as Molecular Compounds, where the element with the positive oxidation state is written first. In many cases, nonmetals form more than one binary compound, so prefixes are used to distinguish them.
So when identifying compounds, how come the prefixes aren't added to the metals and just the nonmetals?

The structural formula for H2 can be drawn as H–H and that for I2 as I–I, where the line indicates a single pair of shared electrons, a single bond. Two pairs of electrons are shared in a double bond, which is indicated by two lines—for example, O2 is O=O. Three electron pairs are shared in a triple bond, which is indicated by three lines—
So do a triple and double bond still count as one bond or is it 2 or 3 bonds when identifying the number of bonds?
