(a)
Interpretation:
Out of the given pair of molecules, the stronger acid is to be predicted.
Concept introduction:
Within acids with similar structures, the strength of each acid depends on the presence of electronegative atoms. The more the electronegativity and number of such atoms, the greater the charge stability and therefore higher the strength.
(b)
Interpretation:
Out of the given pair of molecules, the stronger acid is to be predicted.
Concept introduction:
In acids with the acidic proton attached to the same atom, with the same hybridization, the charge stability depends on the delocalization of the charge in the anion formed on dissociation. Greater the delocalization, i.e., the more the number of atoms over which the charge is spread, greater the stability of the anion (conjugate base) and greater the strength of the acid.
