- 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. 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_forwardGive the structure of an alcohol that could be used to prepare each of the following compounds: a. b. c.arrow_forward
- Draw structural formulas for the alkene that gives each alcohol upon hydroboration-oxidation. (a) (b)arrow_forwardGive 5 uses of acetone. How is acetone prepared commercially? Show equations. Write the equation for the preparation of ketones from secondary alcohols.arrow_forwardAcid-catalyzed dehydration of secondary and tertiary alcohols proceeds through an E1 mechanism. The first step is the protonation of the alcohol oxygen to form an oxonium ion. Dehydration of 3-methyl-2-butanol forms one major and two minor organic products. Draw the structures, including hydrogen atoms, of the three organic products of this reaction. н н :бн н Нас. Нас.
