Vedclass · Answer

(C) The proton-accepting capacity is determined by the basicity of the molecule,which depends on the availability of the lone pair of electrons on the central atom.$NH_3$ has a nitrogen atom with a lone pair of electrons. Nitrogen is more electronegative than phosphorus,but the lone pair in $NH_3$ is more available for donation compared to $PH_3$ because the $N-H$ bond is shorter and the lone pair is in a smaller orbital.$H_2O$ and $H_2S$ are less basic than $NH_3$ and $PH_3$ because oxygen and sulfur are more electronegative,holding their lone pairs more tightly.Therefore,$NH_3$ is the strongest base among the given options and has the highest proton-accepting capacity.

Which of the following has the highest proton-accepting capacity?
