1.	What characteristics do you expect from an electron cleficient hydride with respect to its structure and chemical reactions?
Answer» Solution :Due to lack of SUFFICIENT ELECTRONS, they do not form NORMAL covalent bonds but exist in POLYMERIC state (e.g.,`B_2H_6)`. They are Lewis acied capable of REACTING with Lewis bases.
