Concept explainers
(a)
Interpretation:
Synthesis method of the given compound has to be given from the compound which have the same number of carbon atoms.
Concept Introduction:
Addition of water to
Under acidic conditions, alkyne reacts with water to produce an enol which then immediately converts into
The formed enol and ketone are called keto-enol tautomers.
Tautomerization: It is the process of inter conversion of tautomers and therefore the process can also be called as keto-enol tautomerization.
Hydroboration reaction:
It is the reaction in which an internal alkyne is converted into ketone. The reagents used for the hydroboration oxidation reaction is either
(b)
Interpretation:
Synthesis method of the given compound has to be given from the compound which have the same number of carbon atoms.
Concept Introduction:
Addition of water to alkynes in presence of acid:
Under acidic conditions, alkyne reacts with water to produce an enol which then immediately converts into ketone. For terminal alkynes, there is a need of catalyst which is mercury.
The formed enol and ketone are called keto-enol tautomers.
Tautomerization: It is the process of inter conversion of tautomers and therefore the process can also be called as keto-enol tautomerization.
Hydroboration reaction:
It is the reaction in which an internal alkyne is converted into ketone. The reagents used for the hydroboration oxidation reaction is either
