Document Summary

All chapters were very short, and were put into one slideshow. The proton h+ is a very strong lewis acid. H can combine with elements of different electronegativities to form three main classes of hydrides: with electropositive metals, saline (ionic) hydrides are formed (lih and cah2, with p-block elements, molecular (covalent) hydrides are formed (h2o, ch4 and. H can form metallic hydrides with d and f block elements. Saline hydrides are ionic solids containing h- ions. They react to waster or other proton sources very vigorously. They can deliver h- ions in a metathelical fashion. These elements are isolated by conversion to the chloride then reduction in one of the two following ways: electrolytically (li, na) Example: 2 nacl (l) 2 na (l) + cl2 (cid:894)g(cid:895) down"s process: chemically (k, rb, cs) Example: na (l) + kcl (l) k (g) + nacl (l) They all react with the general equation shown below:
