We would expect a very polar bond, but not so polar that the OH bond is considered ionic. It should be noted that sugar is an unclear word within chemistry. Other planets have water, but they either have it as a gas (Venus) or ice (Mars). Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. Glucose is polar, it can dissolve in water. Is sugar a polar . Many biomolecules arepolymers, meaning that they are made by connecting smaller molecules,called monomers, into larger ones. A physical change occurs when iron rusts. Living things aremade of them and they are made almost exclusively by living things. When sugar dissolves in water, it forms a physical barrier to the movement of charge, which means that it will not be able to conduct charge very easily.. Sugar is homogeneous, which means that is the same throughout the mixture. An ion or group of ions having a negative charge and, characteristically, attracting and having the potential to make ionic bonds with positively charged cations; such negatively charged ions move toward the positive electrode in electrolysis and electrophoresis A weak (only ~5% of the strength of a covalent bond) electrostatic attraction (positive to negative) between atoms in which a hydrogen atom of one polar molecule (most often a water molecule) is attracted to an electronegative atom, especially a nitrogen, oxygen, or fluorine atom, usually of another polar molecule of the same or a different polar substance. However, some atoms (O, N, S) attract electrons more and have a slight negative charge around them.
