they are polar due to the difference in electronegativity. For example HCl. Cl has a higher electronegativity then hydrogen. Another example is KOH. The OH has less electronegativity then the potassium. So therefore they are all polar.
Acids can either polar or nonpolar depending on the type. Many amino acids and nucleic acids are polar, while some amino acids like tryptophan are nonpolar.
Grease is non-polar - vaseline, oil, wax - they are all hydrocarbons, with bonds that aren't polar. To remove a grease from your hands you need a non-polar solvent, not water.
polar covalent
non polar
yes
It is non polar. In amino acids, "polar" or "nonpolar" refers specifically to the side chain; the molecule as a whole is definitely polar, but leucine's side chain is a hydrocarbon with no polar groups.

There are two isomers of Ethenediol. One is polar and the other is nonpolar.
It's ionic, not polar
yes. yes it is.

polar since phthalic acid is 1,2-Benzenedicarboxylic acid, two carboxylic acids are on the aromatic ring.
