$BF_3$

Vedclass · Answer

(A) Lewis base is defined as a species that can donate an electron pair.$BF_3$ is an electron-deficient molecule with an incomplete octet around the central Boron atom ($6$ electrons).Because it has an empty orbital,it acts as a Lewis acid by accepting an electron pair.In contrast,$PF_3$,$CO$,and $F^{-}$ all possess at least one lone pair of electrons that can be donated,allowing them to act as Lewis bases.Therefore,$BF_3$ is the least likely to act as a Lewis base.

$(I)$	Dipole moment	$NF_3 > NH_3 > BF_3$
$(II)$	Covalent bond length	$C-O > N-O > O-H$
$(III)$	Bond order	$C_2 > B_2 > He_2$

Which of these is least likely to act as a Lewis base?
