(2) NaCl(aq) - Sodium chloride dissolved in water (aqueous solution): In its dissolved form, NaCl does not exhibit a regular geometric pattern of particles because the ions are surrounded by water molecules.
(3) H2O(ℓ) - Liquid water: In the liquid state, water does not have a regular geometric pattern. It has a more disordered, liquid structure.
(4) C12 H22 O11(s) - Sucrose (table sugar) in the solid state: Sucrose is a covalent compound, and in its solid state, it forms a regular geometric pattern, characteristic of a crystalline structure.
So, the correct answer is (4) C12 H22 O11(s) - table sugar in its solid state.
