Students can go through AP Inter 1st Year Chemistry Notes 8th Lesson Hydrogen and its Compounds will help students in revising the entire concepts quickly.

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.
