When we have discussed the enol-keto tautomerization of ketones in class, the isomerization has been facililated by an acid or base catalyst, with most ketones heavily favoring the carbonyl isomer at equilibrium. However, samples of the ketone below in its pure form (with no acid, base or water present) contain nearly 10% of the enol form! HO, -90% ~10% From this data, we can infer that the enol isomer of this ketone is particularly stable. Explain the stability of this enol, using terms and ideas that we have discussed in this unit.

Alcohols are important for organic synthesis, especially in situations involving alkenes. The alcohol might be the desired product, or the OH group might be transformed into another functional group via halogenation, oxidation, or perhaps conversion to a sulfonic ester derivative. Formation of an alcohol from an alkene is particularly powerful because conditions can be chosen to produce either the Markovnikov or non-Markovnikov product from an unsymmetrical alkene. Using your reaction roadmap as a guide, show how to convert 4-methyl-1-pentene into 5-methylhexanenitrile. You must use 4-methyl-1-pentene and sodium cyanide as the source of all carbon atoms in the target molecule. Show all reagents needed and all molecules synthesized along the way.
Nonconjugated , -unsaturated ketones, such as 3-cyclohexenone, are in an acid-catalyzed equilibrium with their conjugated , -unsaturated isomers. Propose a mechanism for this isomerization.
The addition of water to aldehydes and ketones occurs rapidly, although it is not thermodynamically favored. What would be the product for the reaction above? Hint: Think of the self-ionization of water and the polarity of the carbonyl group.
1) The carbon-oxygen double bond present in aldehydes and ketones is very polar. What does this mean and how does it arise? 2) The carbon-oxygen double bond is readily attacked by nucleophiles like cyanide ions or ammonia. (i) What do you understand by the term nucleophile? (ii) Which part of the carbon-oxygen double bond is attractive to nucleophiles? 3) Why is there a difference between aldehydes and ketones in their response to oxidizing agents such as potassium dichromate(VI) solution acidified with dilute sulfuric acid?
An important step in one synthesis of carboxylic acids is the deprotonation of diethyl malonate and its alkyl-substituted derivative: Base CH;CH2O OCH,CH3 CH;CH,0 OCH2CH3 H2 Diethyl malonate Base CH;CH,0 °C `OCH,CH3 CH;CH,O OCH,CH3 R Alkyl substituted diethyl malonate NaOH can deprotonate diethyl malonate effectively, but NaOC(CH3)3 is typically used to deprotonate the alkyl-substituted derivative. Explain why.
Organic Chemistry Acid catalyzed dehydration reaction of 2-methyl-1-butanol produces 2-methyl-2-butene as the major product. Also acid catalyzed dehydration reaction of 3-methyl-1-butanol give the same product as major product. Explain the reason why both of the reaction produce the same product as the major product.
