(a)
Interpretation:
The two step curved arrow mechanism of the given decarboxylation reaction including structure of compound X is to shown.
Concept Introduction:
Phosphorylation reaction is the reaction in which phosphate group is attached to an organic molecule. Dephosphorylation is the removal of phosphate group from an organic molecule. Phosphorylation and dephosphorylation reactions are used for activation and deactivation of an enzyme. Decarboxylation reaction is the removal of carbon dioxide from a compound.
(b)
Interpretation:
The electron sink for decarboxylation reaction is to be stated.
Concept Introduction:
The electron sink in the decarboxylation reaction is an atom which withdraws the electrons density of oxygen atom. The removal of electron density from oxygen atom will facilitate the removal of carbon dioxide from the molecule in decarboxylation reaction. Decarboxylation reaction is facilitated by the presence of positive charge on
