Polar molecules have one end that is more negative(it has the electrons more of the time) and one end that is positive(it has the electrons less of the time) In other words the electrons that are shared in the covalent bond are not shared evenly. Therefore, it can attract other things that are polar. Non polar molecules share evenly and do not have a partial charge so do not attract things that have charges.

Polarity is measured on a scale of electronegativity (the electron disparity between two elements that are combined in a compound). The more electrons you take from your partner element in the bonding process, the greater your negative charge, and the greater your electronegativity.
There are three terms to describe the polarity of a given molecular bond:
Ionic
Polar covalent
Non-polar covalent
Ionic is the most polar - essentially, one atom physically takes electrons from another atom, creating a huge electron disparity between the two atoms. This tends to happen in molecules where one atom has very few valence electrons and the other has a lot of valence electrons. Sodium chloride (NaCl) is a good example of an ionic bond.
Polar covalent is the mid-range - technically closer to ionic. This happens when one atom attempts to take electrons from its partner, but cannot quite attract them all to itself. The result is a covalent bond between the two atoms where the valence electrons are "shared," but the sharing is unequal. One atom pulls the "shared" electrons a little closer to itself. Polar covalent bonds usually occur between very electronegative elements; hydrogen paired with elements like oxygen and fluorine almost always creates polar covalent bonds. A good example of a polar covalent bond is found in water (H2O).
Non-polar covalent is the least polar - in fact, it is not polar at all. This occurs when valence electrons are shared equally between two atoms. There is little or no tendency for either atom to pull any of the electrons toward itself. Non-polar covalent bonds can often be seen in molecules with two non-metals. Methane (CH4) is an example of a non-polar covalent bond.
Polar molecules have one end that is more negative(it has the electrons more of the time) and one end that is positive(it has the electrons less of the time) In other words the electrons that are shared in the covalent bond are not shared evenly. Therefore, it can attract other things that are polar. Non polar molecules share evenly and do not have a partial charge so do not attract things that have charges.

A polar molecule
When a molecule is nonpolar it means there are no charges.
A polar molecule in which there is some separation of charge in the chemical bonds, so that one part of the molecule has a slight positive charge and the other a slight negative charge. A common example of polar molecule is water. The water acts as a solvent for polar molecules. A non-polar molecule has no separation of charge, so no positive or negative poles are formed.
Yes, it is bent with two single bonds and two lone pairs
Water and oil doesn't mix because the water is a polar molecule and oil is a non-polar molecule. There will always be more molecules of water than oil.
A molecule is polar if there is a difference in electronegativity between two atoms that are bonded together. Since there is no difference in electronegativity between two oxygen atoms, O2 is nonpolar.
I think you mean HCl and Cl (with an L). HCl is polar because there is a difference in electronegativity between hydrogen (H) and chlorine (Cl). Cl on its own is a single atom and is not bonded to anything for there to be a difference in electronegativity. Cl2 is nonpolar because there is no difference in electronegativity between atoms of the same element.
A polar molecule
No a molecule is a molecule, polar or nonpolar.
No a molecule is a molecule, polar or nonpolar.
Definitely nonpolar.A molecule becomes polar if one of the atoms pulls electrons more strongly than another. But O2 is completely symmetrical--it's just two O atoms that are exactly alike. One can't pull more strongly than another, so it must be nonpolar.
non-polar molecule
if the molecule is symmetrical, then it is nonpolar. if it is NOT symmetrical, it is polar. Ionic bonds form between a metal and a nonmetal.
Since syclohexane is a symmetrical molecule, the sum of the bond dipoles is zero and the molecules is therefore non-polar
Polar.
Dihydrogen monoxide (H2O or Water) is not an example of a nonpolar molecule. It is a polar molecule.
No. Bonds between atoms of the same element are nonpolar. The electronegativity difference between the two atoms is zero, which indicates that the bond is nonpolar.
