A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

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 ...

while others have polar but uncharged side chains. The chemistry of amino acid side chains is critical to protein structure because these side chains can bond with one another to hold a length of ...
