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 ...

Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H bonds which are nonpolar. Alcohol molecules do not attract each other as strongly as water molecules and ...

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 ...

a prototype ionic solid compound. The calculations show that these molecules, despite whether they are homonuclear or heteronuclear, polar or non-polar, small or large, can all react with NaCl and ...
