Sugar is a polar covalent bond because it can't conduct electricity in water. Covalent bonds are most common in elements that are not metal, but can occur when metal and nonmetal elements are physically situated within a short distance of each other. Unless the bond connects two atoms of the same element, there will always be one atom that attracts the electrons in the bond more strongly than the other atom does, as shown in Figure \(\PageIndex{1}\). It is able to bond to itself very well through nonpolar van der Waals interactions, but it is not able to form significant attractive interactions with the very polar solvent molecules. A polar molecule can be identified because it will always have a partial positive and partial negative charge as a result of the polar bonds that are arranged asymmetrically. it dissolves better in hot water than cold water because the hot water has a greater energy to break down the sugar-water bonds. Sugars bonds are also broken apart when a small amount of heat is added.
