Boron halides behave as Lewis base, because of their:
A) ionic nature
B) acidic nature
C) covalent nature
D) electron deficient nature
Correct Answer:
D
Solution :
\[{{B}_{G.S.}}1{{s}^{2}},2{{s}^{2}},2{{p}^{1}}\] It means B has three electrons in valence shell and shares three electrons with halogens that makes total of six electrons. Hence, they are electron deficient compounds.
