Explain with examples Polymeric hybrids.

1.	Explain with examples Polymeric hybrids.
Answer» Polymeric hydrides: These are formed by elements having electro negativity in the range 1.40 – 2.0. These usually exist in the polymeric form in which the monomer molecules are held together in two or three dimensions by hydrogen bridges. Some common examples are : (BeH₂)_n, (AlH₃)_n, (InH₃)_n , (GaH₃)_n , (SpH₄)_n. These are amorphous solids which decompose above 523 K to evolve H₂ gas. Structure. Beryllium hydride exits in the polymeric form involving three center-two electron bonds.
