Question

(A) $H_3BO_3$ acts as a weak monobasic Lewis acid by accepting an $OH^-$ ion from water: $H_3BO_3 + H_2O \longrightarrow [B(OH)_4]^- + H^+$.Option $A$

Vedclass · Accepted Answer

$H_3BO_3$ is a weak monobasic acid as it liberates hydrogen ions as $H_3BO_3 + H_2O \longrightarrow [B(OH)_4]^- + H^+$

Vedclass · Answer

(A) $H_3BO_3$ acts as a weak monobasic Lewis acid by accepting an $OH^-$ ion from water: $H_3BO_3 + H_2O \longrightarrow [B(OH)_4]^- + H^+$.Option $A$ is considered incorrect because $H_3BO_3$ does not act as a Brønsted-Lowry acid (proton donor) by simple dissociation; rather,it acts as a Lewis acid by accepting an $OH^-$ ion from water,which subsequently releases $H^+$ ions.
