What characteristics do you expect from an electron-deficient hydride with respect to its structure and chemical reactions?

##### Solution :-

To form a regular bond, an electron-deficient hydride does not have sufficient electrons in which 2 electrons are shared by 2 atoms.

e.g., B2 H6,

Al2 H6 etc.

Conventional Lewis structures cannot able to represent these hydrides. B2H6, for example, contains 4 regular bonds and 2 3 centered-2 electron bond.

They have a tendency to accept electrons because, these hydrides are electron-deficient. Hence, they act as Lewis acids.

$$B_{2}H_{6}+2NMe\rightarrow 2BH_{3}.NMe_{3}B_2​H_6​$$

$$+2CO→2BH_3​.CO$$
