Vedclass · Answer

(C) Lewis base is a species that can donate a lone pair of electrons.According to the Bronsted-Lowry theory,the conjugate base of a strong acid is a weak base.Among the given options,$HCl$ is a strong acid,so its conjugate base $Cl^-$ is the weakest base.$H^-$ is the conjugate base of $H_2$,$OH^-$ is the conjugate base of $H_2O$,and $HCO_3^-$ is the conjugate base of $H_2CO_3$.Since $HCl$ is the strongest acid among the corresponding conjugate acids,$Cl^-$ is the weakest base.
