In thermodynamics, high entropy state, as contrasted with a low entropy state, is said to be an disordered, disorganized, or spread out (low density) state of atoms and molecules. [1]

This rule, however, is generally only true in comparing a gas state (chaotic) to a liquid state (medium order) to a solid state (ordered) to one at absolute zero (perfect order).

In defining entropy values to different molecules, the procedure used involves assigning simple component atoms and molecules arbitrary (often zero value) measures of free energy and enthalpy, at their standard conditions, and using this basis to make thermodynamic tables of entropy and enthalpy values for different reactions, and using reaction algebra to assign entropy values to more complex structures. In an aside, the universe prior to the inception of the big bang is often theorized to have been in a low entropy state, about the size of a golf ball. [2]
