Concept explainers
(a)
Interpretation: Which one of the given pair of molecules should have the more acidic
Concept introduction:
The strength of an acid depends on the stability of the conjugate base formed by the removal of the proton. The higher the stability of the conjugate base, the stronger the acid.
The stability of the conjugate base depends on several factors, the electronegativity of the atom that bears the negative charge, possible delocalization of the charge because of resonance, and the hybridization of the atom that bears the charge.
If the electronegativity and hybridization are similar, the resonance stabilization of the charge determines the stability of the conjugate base. The more the number of atoms over which the charge is delocalized, the higher the stability of the conjugate base, and hence the higher the strength of the acid. Aromaticity also plays a role in stabilization. The order of stability of cyclic conjugate bases with double bonds is
