The equilibrium favours the products.

Vedclass · Answer

(A) The equilibrium reaction is: $(CH_3)_3CO^- + H_2O \rightleftharpoons (CH_3)_3COH + OH^-$.Acid-base reactions always proceed in the direction of forming the weaker acid and the weaker base.Comparing the $pK_a$ values: $H_2O$ $(pK_a = 15.7)$ is a stronger acid than $(CH_3)_3COH$ $(pK_a = 18)$.Since the reaction proceeds from the stronger acid to the weaker acid,the equilibrium lies to the right (towards the products).Therefore,$(CH_3)_3CO^-$ is a stronger base than $OH^-$,and the equilibrium favours the formation of the weaker base $(OH^-)$ and the weaker acid $((CH_3)_3COH)$.Thus,$t$-butoxide is the dominant anionic species is incorrect,and the equilibrium favours the products.
