1.	What characteristics do you expect from an electrondeficient hydride with respect to its structure and chemical reactions.
Answer» ctron deficient hydrides won’t have sufficient number of electrons to form COVALENT bond. The structure of these hydrides are trigonal planar. The best example of electron deficient hydrides is BF3 which is shown in first diagram.The hydrides acts as Lewis acids, i.e., pair of electron acceptor as shown in second diagram .To compensate the electron DEFICIENCY these hydrides exist in POLYMERIC forms.Example are and etc.,We know that hydrides with electron deficiency are very REACTIVE. These hydrides react with “metals and non-metals” to form compounds readily.
