Sugar: Sugar is a crystalline solid that is mainly used as a sweetener for beverages and foodstuffs. This is a nonpolar covalent bond. Answer Save. sucrose is a polar, covalently bonded molecule. Join Yahoo Answers and get 100 points today. octane is a completely saturated hydrocarbon and is therefore non-polar. Favorite Answer . Since sucrose and water have the same molecular polarities, based on "like dissolves like", sucrose will dissolve in water. Lv 7. a) Water is a polar solvent and hexane (C6H14) is a nonpolar solvent. a big organic compound with that many oxygen atoms is always polar. Summary. Both C-O and O-H bonds are polar in the direction of the oxygen atom. Non polar solvents are good at dissolving non polar saw utes, and that's because the similar type of solvent and saw you are able to interact kind of on a particulate level. What do your solvents mix with? Sugars generally are polar. Is sucrose ionic, polar, or non polar? Iggy. A polar molecule is a molecule containing polar bonds where the sum of all the bond's dipole moments is not zero. Examples of household non-polar … Ethanol is a very polar molecule due to its hydroxyl (OH) group, with the high electronegativity of oxygen allowing hydrogen bonding to take place with other molecules. A non-polar compound may be non polar because there is (almost) no polarity in the bonds or because of the symmetrical arrangement of polar bonds. CHESSLARUS. A molecule with polar bonds could still be overall non-polar if it has a spatially symmetric geometric structure. When analyzing the structure, it is obvious sucrose is polar because of the hydroxide bonds. Answer this question. That is why gasoline will mix with it (nonpolar) and water will mix with it (polar). disaccharides have many -OH groups. Sucrose is disaccharide formed by a glucose and a fructose molecule linked by glycosidic linkage. Based on the answers to Questions 1 and 2, predict whether the intermolecular forces (forces between molecules) are stronger in polar or nonpolar substances. Type of Electrolyte 3. Because sucrose is a polar molecule, it dissolves in water. The Machine.
