Vedclass · Answer

(A) Lewis base is defined as a substance that can donate a lone pair of electrons. $NH_3$,$H_2O$,and $OH^-$ all possess at least one lone pair of electrons on the central atom,allowing them to act as Lewis bases. $BF_3$ is an electron-deficient molecule with an incomplete octet (only $6$ electrons around the central $B$ atom). Therefore,$BF_3$ acts as a Lewis acid because it accepts an electron pair,not a Lewis base.

Which of the following is $NOT$ likely to act as a Lewis base?
