Concept explainers
(a)
Interpretation:
Given the each set of compounds whether it is a hemiacetal or neither should be identified.
Concept Introduction:
Addition reaction: Addition of an alcohol or other organic compound to the carbon double bond to give a carbon-oxygen single bond.
Hemiacetal: A compound with both an alcohol like (-OH) group and ether like (-OR) group bond to the carbon atom was at one time the
Acetal formation: The small amount of acid catalysts is added to the reaction of an alcohol with an aldehyde or
(b)
Interpretation:
Given the each set of compounds whether it is a hemiacetal or neither should be identified.
Concept Introduction:
Addition reaction: Addition of an alcohol or other organic compound to the carbon double bond to give a carbon-oxygen single bond.
Hemiacetal: A compound with both an alcohol like (-OH) group and ether like (-OR) group bond to the carbon atom was at one time the aldehyde carbonyl carbon.
Acetal formation: The small amount of acid catalysts is added to the reaction of an alcohol with an aldehyde or ketone, the hemi-space initially formed is converted into an acetal or a ketal substitution reaction.
