Final answer:
Sucrose separates into individual sugar molecules upon dissolving in water, but remains chemically unchanged without forming new bonds or dissociating into glucose and fructose.
Step-by-step explanation:
When sucrose is added to water, it doesn't dissociate into glucose and fructose, form a chemical bond with water, or evaporate. Instead, water dissolves sucrose by separating the individual sugar molecules, disrupting the intermolecular attractive forces. However, the covalent bonds within the sucrose molecule between carbon, hydrogen, and oxygen atoms remain intact. Once dissolved, sugar molecules are surrounded by a shell of water molecules, but this hydration shell does not represent a strong bond like that of ions in solution. Sucrose contains many –OH groups that are able to form hydrogen bonds with water molecules, aiding in the formation of a sucrose solution.
When sucrose, which is a molecular compound, is added to water, it dissolves to form a sucrose solution. The covalent bonds between the carbon, hydrogen, and oxygen atoms in sucrose remain unchanged. The individual sugar molecules are separated as the attractive forces between them are disrupted by the water molecules. The sugar molecules are also hydrated, with the -OH groups forming hydrogen bonds with the water molecules.
