- 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_forwardWhy can’t 2-methyl-2-propanol be prepared by the reduction of a carbonyl compound?arrow_forwardAcetylene reacts with sodium amide in the presence of propyl halide produces aldehyde produces ketones It produces 2-pentanearrow_forward
- Compare the acidity of phenols with the acidity of alcohols.arrow_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. 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_forward
