Each molecule consists of a long non-polar covalent hydrocarbon ‘tail’ and a polar, ionic ‘head’ where the charge is. This structure explains the cleansing action of soap as the non-polar ...

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 ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons ... Electrons can be shared unequally in a molecule, creating a polar molecule.

Sucrose has many O–H bonds which are polar. These polar areas are shown with a + near the hydrogen atom and a − near the oxygen atom. The second space-filling model shows two sucrose molecules held ...
