Sucrose is disaccharide formed by a glucose and a fructose molecule linked by glycosidic linkage. Answer for question: Your name: Answers. Non-polar molecules have electrical charges that are more equally distributed. This is because many possess structures in the form C-O-H. Since sucrose and water have the same molecular polarities, based on "like dissolves like", sucrose will dissolve in water. c) Calculate the mass of solute needed to prepare 1300 mL of a 7.0 % (m/v) Wn2ApO4 solution. Both C-O and O-H bonds are polar in the direction of the oxygen atom. The hydroxyl group attached to one of the carbon atoms is what gives ethanol its polarity. Favorite Answer . Is Sucrose Polar . Because sucrose is a polar molecule, it dissolves in water. Polar molecules also form when the spatial arrangement of chemical bonds leads to a more positive charge on one side of the molecule than the other. 1 decade ago. Other examples include sugars (like sucrose), which have many polar oxygen–hydrogen (−OH) groups and are overall highly polar. 0 0. If sucrose was nonpolar, it would not dissolve in water or would dissolve slightly. On the other hand, octane and water do NOT have similar polarities, so octane will not dissolve in water. Example 4. Hydrogen has an electronegativity of 2.1, and chlorine has an electronegativity of 3.0. This is understood by the chemical axiom "like dissolves like." Extracellular sucrose is hydrolyzed to yield glucose and fructose in a reaction catalyzed by the sucrase domain of sucrase-isomaltase (Conklin et al. What is polar and non-polar? This is understood by the chemical axiom "like dissolves like." And those interactions health the dissolution occur. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. likes dissolve likes! Sucrose is a polar molecule. We took 6 tests tubes and filled 3 of them 1/3 of water. In addition, the oxygen atom has a lone pair of electrons opposite from the C-O and O-H bonds. You have a nonpolar covalent bond anytime the two atoms involved in the bond are the same or anytime the difference in the electronegativities of the atoms involved in the bond is very small. Lv 4.
