These type of hydrides do not have sufficient number of electrons to form normal covalent bonds.example : BF3 has only 6 electrons in its valance shell, these hydride are trigonal planar in shape.
due to electron deficient it acts as Lewis acid. { A lone pair acceptor}
To make up the deficiency of electrons , these hydride exist in polymeric form eg., B2H6, B4H10 etc. These are very reactive.these react with metals and non-metals and their compounds readily.
e.g., B2H6 + 3O2(g) ---> B2O3 + 3H2O .
