Exhibit 19-2
Consider the data below to answer the following question(s).
Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and aldehydes.The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid.Nitriles can also be hydrolyzed to carboxylic acids using aqueous base.Unfortunately,when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated.
-Refer to Exhibit 19-2.Formulate a reasonable mechanism for the reaction of the cyanohydrin of benzaldeyhe,shown above,with aqueous NaOH.Show all intermediate structures and all electron flow with arrows.
Treatment
The act of providing medical care or therapy to address or heal a disease, disorder, or injury.
Stimulus
A scenario or event that triggers a response in an organism.
Conditioned Stimulus
An initially neutral signal that, upon being paired with an unconditioned stimulus, triggers a learned response.
Classical-Conditioning Principles
Fundamental concepts of classical conditioning, such as stimulus generalization, extinction, and spontaneous recovery, that describe how conditioned responses are acquired, maintained, and eliminated.
