Molecular Polarity

What is electronegativity?

An atom’s ability to attract 2 electrons in a covalent bond

Are bonds between atoms with the same electronegativity polar or non-polar?

Non-polar

Are bonds between atoms with similar electronegativities polar or non-polar?

Non-polar

If all the bonds in a molecule are non-polar, the molecule itself will be…polar or non-polar?

Non-polar

If a molecule has a dipole, then it is…polar or non-polar?

Polar

If a molecule contains polar bonds all on the same side of the central atom, is the molecule non-polar or polar, and why?

Polar, because it has a dipole

If atoms around the central atom in a molecule are the same, the molecule is…polar or non-polar?

Non-polar

If atoms around the central atom in a molecule are not the same, the molecule is…polar or non-polar?

Polar

If a molecule is symmetrical, will it be polar or non-polar, and why?

Non-polar, because the dipoles cancel out

If difference in electronegativity between two atoms in a bond < 0.5, the bond is…polar or non-polar?

Non-polar

If difference in electronegativity between two atoms in a bond > 0.5, the bond is…polar or non-polar?

Polar
