A substance that contains polar covalent bonds may not be overall polar ... This means that the molecule itself is non-polar due to symmetry.

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons ... Alcohol has one O–H bond which is polar, but a large ...

with a large difference indicating a polar covalent bond (e.g., H-F bond) and a small difference indicating a non-polar covalent bond (e.g., C-C bond). Electronegativity is crucial for explaining ...

high surface tension relatively high viscosity All ionic lattices and polar covalent molecules are: soluble in water and other polar solvents insoluble in non-polar solutions (eg hexane ...
