WebCovalent and ionic bonds represent two fundamental forms of bonding between atoms. In contrast to bonds with significant covalent character, ionic bonds are of limited use for the spatial structuring of matter because of the lack of directionality of the electric field around simple ions. We describe a predictable directional orientation of ionic bonds that contain … WebCleavage of polymers back to monomers occurs by hydrolysis reactions, where a molecule of water is split (hydrolyzed) to -OH and H. Hydrolysis reactions break the bonds linking two subunits. This is exactly the reverse of a dehydration reaction.
