Interpretation: To prepare the given products from the reaction of a
Concept introduction: To increase the carbon chain, substituting an alkyl group on alpha carbon of a carbonyl group is called alkylation.
Alkylation is carried out by removing a proton from an alpha carbon with a strong base, LDA, to form an enolate ion and then adding an appropriate alkyl halide. The alkylation is a

- How could each of the following compounds be prepared from cyclohexanone?arrow_forwardDraw the product of the reaction between a ketone and an alcohol. Include all hydrogen atoms in the product. How would you classify the product of the reaction? Note that a hemiacetal formed from a ketone is also called a hemiketal; an acetal formed from a ketone is also called a ketal. The product is an alcohol. The product is a ketal The product is a ketone. The product is a hemiketal.arrow_forwardDraw the structure of the major organic product for the following reaction: Br 0 + N Harrow_forward
- Prepare the following substances from aldehydes or ketonesarrow_forwardPrepare the following substances from different aldehydes or ketonesarrow_forwardHydration of aldehydes and ketones can be catalyzed by acid or base. Bases catalyze hydration by: protonating the carbonyl oxygen making the carbonyl group more electrophilic employing hydroxide ion, which is a better nucleophile than water making the carbonyl group less electrophilic shifting the equilibrium position of the reaction to favor productsarrow_forward
- prepare these compounds from benzene H.W CH CH2 COOH COOH SOH HOS SO,H COOHarrow_forwardDraw the enol form of the following ketonearrow_forwardWhat explains why many aldehydes and ketones can undergo self-condensation reactions in basic conditions? The alpha carbon can lose a proton and act like a nucleophile and the carbonyl carbon is an electrophile. The alpha carbon can gain a proton and act like an electrophile and the carbonyl carbon is a nucleophile. The oxygen of the carbonyl group can attack the carbon of the carbonyl group. Only esters can undergo self-condensation reactions.arrow_forward
