What is the difference between a polar molecule and a dipole?

Answer 1

a polar molecule is a MOLECULE containing atoms of enough electronegativity difference to make the electrons to be more likely to be closer to the more electronegative atoms. A hydrogen bond is a type of BOND or interaction per se that results between polar molecules due to the electrical differences between a partial positive part and a partial negative part.

Answer 2

A polar bond is a covalent bond in which electrons are shared unevenly due to differences in the electronegativities of the bonded atoms, usually resulting in one atom having a partial negative charge and the other a partial positive charge.

A polar molecule is a group of covalently bonded atoms that that has a partial negative at one end and a partial negative charge at the other because it contains at least one polar bond.

Answer 3

There are several types of covalent bonding and those are stated below along with an example.

Polar molecules with polar bonds - Hydrogen Chloride

Non-polar molecules with polar bonds - Sulfur Hexafluoride

Non-polar molecules with non-polar bonds - Ozone

Answer 4

Dipole is more of a general term for two point charges that are separated by a distance and have an electric field between them. Every polar bond creates a dipole, but a molecule containing polar bonds might not have a total dipole moment.

These occur in cases of symmetry where dipole vectors cancel each other out.* For example, all four bonds in carbon tetrachloride (CCl4) are polar because chlorine is very electronegative. This results in four dipoles where all four vectors point from the central carbon to one of the four chlorines. But because CCl4 is tetrahedral, the vectors point in "opposite" directions and cancel each other out because they have the same magnitude. (If you draw it out, you notice that the vectors aren't really in opposite directions, but their components in the x, y, and z are opposite).

* If the content about vectors is confusing, here's the short version: between two atoms such as carbon and chlorine where there is a significant electronegativity difference, a polar bond is created. Chlorine is so electronegative that it will pull electron density from carbon. This creates a difference in electric potential and an electric field between the positive carbon and negative chlorine. We represent this field by an arrow pointing from carbon to chlorine (this is the vector). You sum these vector contributions within a molecule to determine if the overall molecule has a dipole moment. If the vector are oriented symmetrically, they could cancel each other out and no molecular dipole is created.

Answer 5

A polar molecule is a molecule with an uneven distribution of electron density, leading to partial positive and negative charges. A dipole is a pair of equal and opposite charges separated by a distance, which can occur within a polar molecule. In essence, a polar molecule may have a dipole moment, reflecting the overall polarity of the molecule.
