The organic liquids toluene (C₇H₈) and cyclohexane (C₆H₁₂) are combined to form a solution. Toluene and cyclohexane are both nonpolar so they are completely miscible. In the solution formation, compare the entropy of the system to the separate pure liquids.

Dicycloverine (C₁₉H₃₅NO₂) also known as dicyclomine is a drug used to cure gastrointestinal tract spasms. The conversion of the free-base form (C₁₉H₃₅NO₂) of dicycloverine to the protonated hydrochloride form (C₁₉H₃₆ClNO₂) using one equivalent of HCl is shown below (Note: Not all carbons and hydrogens are shown. Each "corner" represent a carbon bonded to the correct number of hydrogens in order to make a total of four bonds):

Based on the given structure, determine which form of dicycloverine is more soluble in water.

Identify if the following process is endothermic or exothermic: Dissolving NaCl in H₂O increases the temperature of the solution.

Arrange the following solute-solvent interactions in order of increasing strength of attraction.

i. CS₂ in CCl₄

ii. Na⁺ in H₂O

iii. CH₃NH₂ in H₂O
