When trichloroacetaldehyde is dissolved in water, almost all of it is converted to the hydrate. Chloral hydrate, the product of the reaction, is a sedative that can be lethal. A cocktail laced with it is known—in detective novels, at least—as a “Mickey Finn.” Explain why an aqueous solution of trichloroacetaldehyde is almost all hydrate.
Acetals are formed from the reaction of two alcohols with a carbonyl under acidic
conditions. Acetal formation is faster with 1,2-ethanediol than with two methanol
molecules.
Choose the factor that explains the difference in reaction rates.
A) The reaction with 1,2-ethanediol has a
lower AH (enthalpy) of reaction.
B) The reaction with 1,2-ethanediol has a
higher AH (enthalpy) of reaction.
C) The reaction with 1,2-ethanediol has a
more favorable entropy of reaction.
