- Hydration 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_forwardAcetylene reacts with sodium amide in the presence of propyl halide produces aldehyde produces ketones It produces 2-pentanearrow_forwardPrepare the following compounds starting from benzaldehyde and the appropriate ketone. Provide reactions for preparing the ketones starting from aromatic hydrocarbon compounds.arrow_forward

- Aldehydes and ketones react with one molecule of an alcohol to form compounds called hemiacetals, in which there is one hydroxyl group and one ether-like group. Reaction of a hemiacetal with a second molecule of alcohol gives an acetal and a molecule of water. ROH, H+ OH OR Aldehyde/ketone Alcohol ROH, H+ Draw the structural formulas for the hemiacetal and the acetal formed between the following compounds: OH OH OR OR • Use the wedge/hash bond tools to indicate stereochemistry where it exists. + H₂Oarrow_forwardAldehydes and ketones react with one molecule of an alcohol to form compounds called hemiacetals, in which there is one hydroxyl group and one ether-like group. Reaction of a hemiacetal with a second molecule of alcohol gives an acetal and a molecule of water. We study this reaction in Chapter 16. Draw structural formulas for the hemiacetal and acetal formed from these reagents. The stoichiometry of each reaction is given in the problem.arrow_forwardList the following compounds in order of increasing water solubility: a.ethoxyethane b.propanoic acid c.pentane d.1 butanolarrow_forward
