- Why is the Aldol reaction often called an Aldol condensation? 1) The initially formed b-hydroxy carbonyl compound loses an oxygen atom 2) The initially formed b-hydroxy carbonyl compound loses a hydrogen atom 3) The initially formed b-hydroxy carbonyl compound loses water 4) The initially formed b-hydroxy carbonyl compound loses a hydroxyl grouparrow_forwardAnswer the following questions about curcumin, a yellow pigment isolated from turmeric, a tropical perennial in the ginger family and a principal ingredient in curry powder.a.In Chapter 11, we learned that most enols, compounds that contain a hydroxy group bonded to a C=C, are unstable and tautomerize to carbonyl groups. Draw the keto form of the enol of curcumin, and explain why the enol is more stable than many other enols. b.Explain why the enol O—H proton is more acidic than an alcohol O—H proton. c.
