Question
What is the more stable form of 1,3- cyclohexanedione? Of the compounds listed below, which one has (acidic) alpha hydrogens? Which of the following compounds is the strongest carbon acid (which has the most acidic H's?) Will the following reaction occur to greater than 99% completion (the base is LDA)? Which of the following compounds is most reactive with respect to alkaline hydrolysis (sci) -C substitution with OH- as nucleophiley)? Why doesn't nucleophilic acyl substitution stop at the tetrahedral intermediate? The nucleophile is too basic. The tetrahedral intermediate rapidly converts to an enol species which, in turn, cleaves to form the products. The tetrahedral intermediate ejects a heteroatom leaving group to form a relatively stable carbonyl containing compound. There is no tetrahedral intermediate. Which of the following anions is the most stable (If resonance exists, only one resonance structire is drawn) In the H + catalyzed halogenation of ketones, the rate-determining step is Protonation of the ketone Loss of an a-hydrogen from the protonated ketone to form an enol intermediate. Attachment of a halogen atom to the enol intermediate. Deprotonation to form a=haloketone product (last step). What is the first step in the nucleophile-include (base-neytral) mechanism for nucleophilic Protonation of the carbonyl group Removal of an alpha-proton Attachmeny of the nucleophile to the carbonyl group Loss of the leaving group. What is the product of the followingh reaction? Name of the following compound: Propyl butanoate Butyl propanonate Propane carbonylbutyrate Propyl propionate Which compound below (containing -OH group) is most easily dehydrated when treared with warm, dilute acid? (thik about the stability of the product that would form for each) What will be the major product of the following reaction? Give the organic product(s) formed in each of the following reactions. the missing reactant in each reaction below (in some cases there is more than one possible right answer); All byproducts may not be shown in some reactions Explain why ethanal is a stronger carbon acid than ethane (to receive full credit you must draw appropriate structure(s) to reinforce your explanation)
