To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated OH CHCOOH HO CN OBU H HCEN H NAOH H20...

11. The bowhead whale, which has a large head that is up to 40% of its body length, lives in the Arctic. The age of the bowhead whale is estimated by measuring the extent to which the amino acid Asp (aspartic acid), which is found in the eyes of the whales, has undergone racemization. For example, 100% of (L.) aspartic acid racemizes towards a more 50:50 mixture of (L) and (D-aspartic acid Provide a complete, stepwise, curved-arrow mechanism for the...

just need (e) to (h)
5. Molecules with an-OH group directly bonded to a C-C sp hybridized carbon are called "enol"'s. The types of chemical reactions which enols undergo are substantially different from those of normal alcohols. By considering the Brensted-Lowry and Lewis acid/base reactivity of an enol, you can predict a few of these differences. (a) Ethenol, the simplest "enol", can react as a BL. base in three different places, by gaining a proton at either of the two...

Conceptual Checkpoint 18.32 The presence of additional nitro groups can have an impact on the temperature at which a nucleophilic aromatic substitution will readily occur. Consider the following example Cl он 1) NaOH 2) Hyo NO2 NO2 When both R groups are hydrogen atoms, the reaction readily occurs at 130°C. When one of the R groups is a nitro group, the reaction readily occurs at 100°C. When both R groups are nitro groups, the reaction...
