Define the term Electron deficient.

1.	Define the term Electron deficient.
Answer» The hydrides which do not have sufficient number of electrons to form normal covalent bonds is called electron deficient hydride. For example, hydride of group 13 (BH₃, AlH₃, etc.). They are known as Lewis acids i.e., electron acceptors. To make up their deficiency they generally exist in polymeric forms such as B₂H₆, Al₂H₆, etc.
