Vedclass · Answer

(D) Lewis base is a substance that can donate a lone pair of electrons.$NH_3$,$PH_3$,and $(CH_3)_3N$ all have a lone pair of electrons on the central atom (nitrogen or phosphorus) and act as Lewis bases.$HN_3$ (Hydrazoic acid) does not have a lone pair available for donation in the same manner as the others and is generally considered to act as a Lewis acid in specific contexts due to its electron-deficient nature.Therefore,the correct option is $D$.
