- Answer 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. Why is curcumin colored? d.Explain why curcumin is an antioxidant.arrow_forwardAcetal derivatives of aldehydes and ketones are prepared by an acid-catalyzed dehydration reaction with alcohols or diols. Using more pictures than words, draw a reaction and a mechanism that shows the formation of acetal.arrow_forwardThe reaction of a ketone with an alcohol in acidic conditions will result in: an alkane an acetal a geminal (gem) diol an alkenearrow_forward
