Vedclass · Answer

(A) The stability of the conjugate base depends on the ability of the molecule to disperse the negative charge.$(i)$ Phenoxide ion: The negative charge is delocalized over the benzene ring.(ii) $4-$Hydroxypyridine conjugate base: The negative charge on oxygen is delocalized into the pyridine ring,specifically onto the electronegative nitrogen atom,making it the most stable.(iii) Cyclohexoxide ion: There is no resonance stabilization for the negative charge,making it the least stable.Therefore,the order of stability of the conjugate base is $ii > i > iii$.

The order of stability of the conjugate base of the given acids is:
$(i)$ Phenol
(ii) $4-$Hydroxypyridine
(iii) Cyclohexanol
