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 ... but a large portion of the molecule is made up of C–H bonds which are nonpolar. Alcohol ...

This causes the covalent or ionic bonding that holds atoms or ions ... But, the carbon–hydrogen (C–H) bonds in the rest of the alcohol molecule are nonpolar. In these bonds, the electrons are shared ...

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 ...
