* Sugar (sucrose) is a covalent compound. The carbon, hydrogen, and oxygen atoms in sugar are held together by covalent bonds, sharing electrons.

* Water (H2O) is also a covalent compound, with hydrogen and oxygen atoms sharing electrons.

When sugar dissolves in water, it doesn't break apart into ions (charged particles). Instead, the sugar molecules become surrounded by water molecules, forming a homogeneous mixture.

Ionic solutions, on the other hand, involve the dissociation of ionic compounds into ions when dissolved in water. For example, table salt (NaCl) dissolves in water to form sodium ions (Na+) and chloride ions (Cl-).
