9.) Rank the following from most acidic to least acidic and explain your choices in detail: The image displays four different chemical structures, labeled A through D:**A.** The structure consists of a benzene ring with two substituents: an -OH (hydroxyl) group and a -COOCH₃ (methoxycarbonyl) group. These groups are attached to the benzene ring, with the -OH group adjacent to the -COOCH₃ group, suggesting an ortho relationship.**B.** This structure also features a benzene ring, with three substituents: an -OH group, a -CH₃ (methyl) group, and a -COOCH₃ (methoxycarbonyl) group. The methyl group is positioned directly adjacent to the -OH group, and the -COOCH₃ group is adjacent to the methyl group.**C.** Similar to A, this structure has a benzene ring with two substituents: an -OH (hydroxyl) group and a -COOCH₃ (methoxycarbonyl) group. In this structure, the groups are placed in the para position, opposite each other on the benzene ring.**D.** The structure contains a cyclohexane ring with two substituents: an -OH (hydroxyl) group and a -CH₃ (methyl) group. These groups are attached to the same carbon atom on the ring, indicating a tertiary alcohol structure. Each structure represents a different compound with unique chemical properties, useful in various chemical and pharmaceutical applications.

Break open your cyclohexane ring to make n-hexane (C6H14). (You will need two extra hydrogen atoms to the terminal carbon atoms to complete your model). Is hexane flexible or rigid? The melting point of cyclohexane is 6o C whereas the melting point of hexane is -94o C. Can you suggest a reason for this based on the structures you have made?
