Which of the following is least likely to behave as Lewis base?
A.
$$N{H_3}$$
B.
$$B{F_3}$$
C.
$$O{H^ - }$$
D.
$${H_2}O$$
Answer :
$$B{F_3}$$
Solution :
$$B{F_3}$$ is an electron deficient species, thus behaves like a Lewis acid.
$$\because {\text{Bond}}\,{\text{order}}\, = \frac{{{N_b} - {N_a}}}{2}$$
