HYDROGEN

In CHAPTER 17 - HYDROGEN (15 Pages)-  the preferential polarization of hydrogen (not discussed in any other book) is discussed. Why does hydrogen form a three dimensional lattice when it combines with alkali metals (and not when it combines with electronegative elements), why does the stability of the hydrides decrease down the group in contrast to the respective oxides, why do molecules such as HF₃, HCl₃ are not formed and why is there  no intra molecular hydrogen bonding in CH₃COOH are explained.

     Further, the reason for 1:3 ratio for ortho and para hydrogen, the reason for the increase in oxidation potential with decrease in hydrogen ion concentration, the reason why, say, the electron of the hydrogen atom has same energy when it remains in the 3s, 3p, 3d orbitals are also discussed. 

    The effect of squeezing hydrogen under ultra high pressure ( Ho-Kulang Mao and Russel Homley – 1989) is mentioned.

    Present status of cold fusion given.
