Answers (1)
R Rakesh

Answer-

Electron-deficient hydrides do not have required electrons to form a regular bond in which two electrons are shared by two atoms. e.g. B_{2}H_{6},Al_{2}H_{6} etc

Because of electron deficiency, they have the tendency to accept electrons. hence they act as Lewis acid.

\\B_{2}H_{6}+2NMe\rightarrow 2BH_{3}.NMe_{3}\\B_{2}H_{6}+2CO\rightarrow 2BH_{3}.CO
