Concept explainers
Interpretation:
The final product obtained in the given reaction sequence is to be determined.
Concept Introduction:
Dianions can be prepared from
Protons on the
In a given dihalo alkyl compound, the bromide ion is a good leaving group than the chloride ion.
Sodium azide is a salt and dissociates as sodium and azide ions. Azide ion is a strong nucleophile and thus it can replace the halogen atom in the given alkyl halide by an
Potassium carbonate acts as a base and thus depronates the hydroxyl group in the hydroxyl acid derivative.
