AP Inter 1st Year Chemistry Notes 8th Lesson Hydrogen and its Compounds
→ Hydrogen has a unique position in the periodic table. It can be placed in IA group as well as VII A group.
→ Hydrogen has three isotopes : protium (1H1), Deuterium (1H2(or) D) and Tritium (1H3 or T)
→ Hydrogen combines with all elements except noblegases to form the binary compounds, called hydrides.
→ s-block elements forms ionic hydrides, p – block elements forms covalent hydrides and d – block, f- block elements forms Interstetial hydrides.
→ Water that gives good lather quickly with soap is called soft water and the water which does not give lather easily with soap is called hard water.
→ Temporary hardness is due to presence of bicarbonates of Ca, Mg.
→ Permanent hardness is due to presence of chlorides, sulphates of Ca, Mg.
→ H2O2 is prepared by the electrolytic oxidation of 50% H2SO4 solution (or) auto oxidation of 2-Alkyl anthraquinol.
→ H2O2 has non-planar structure [open book structure] in gas phase and solid phase.
→ Heavy water is used as moderator in nuclear reactors.
→ Hydrogen has potential for using it as a non – polluting fuel.
