(a)
Interpretation:
Representation of proton transfer reaction by curved arrows with mentioning acids, bases and products of the given equilibrium reactions are needed to work out.
Concept introduction:
According to Bronsted-Lowry concept, acid is proton donor and base is proton acceptor. Curved arrows show the reaction mechanism of the acid-base reaction.
The mechanism of proton transfer always involves at least two curved arrows. One arrow should show the abstraction of hydrogen by the base and the other arrow shows the gain of negative charge by the acid.
The favored position of equilibrium is predicted by comparing the stability of the acids or the bases in each side of the given reactions.
The lone pair of conjugate base involving in resonance in a molecule will have greater stability as compared to bases having single anion. The stability is due to resonance stabilization energy.
To draw: the proton transfer reaction mechanism of the given reactions by using curved arrows with mentiontioning acid, bases and predict the direction of favored position of equilibrium.
