(a)
Interpretation:
The mechanism for the acid-catalyzed reaction of cyclohexanone with ethylene glycol to give cyclohexanone ethylene acetal is to be proposed.
Concept introduction:
In the acid catalyzed reaction of cyclohexanone, proton first attacks on cyclohexanone and protonation takes place. After protonation the addition of alcohol is done. In the last step deprotonation occurs to get the final product.
(b)
Interpretation:
The mechanism for the acid-catalyzed hydrolysis of cyclohexanone ethylene acetal is to be proposed.
Concept introduction:
Hydrolysis is defined as the phenomenon in which the chemical breakdown of a compound takes place by its reaction with water. A
(c)
Interpretation:
The mechanisms for the acid-catalyzed reaction of cyclohexanone and for the acid-catalyzed hydrolysis of cyclohexanone are to be compared in reverse order and the similarities between them are to be stated.
Concept introduction:
Hydrolysis is defined as the phenomenon in which the chemical breakdown of a compound takes place by its reaction with water. A functional group is defined as a portion of the compound that is a recognizable group of bound atoms.
(d)
Interpretation:
The mechanism for the acid-catalyzed hydrolysis of acetal is to be proposed.
Concept introduction:
Hydrolysis is defined as the phenomenon in which the chemical breakdown of a compound takes place by its reaction with water. A functional group is defined as a portion of the compound that is a recognizable group of bound atoms.
