Isotopes of hydrogen, properties of H₂, hydrides (ionic, covalent, metallic), water, hydrogen peroxide, and industrial production of hydrogen.
Strength of hydrogen bonds: Directly proportional to the electronegativity of the bonded atom, Structure of H₂O₂: Open-book structure.
Confusion between different hydrides; neglecting the anomalous properties of water and hydrogen bonding; errors in reaction-based problems for hydrogen peroxide.
Basics of bonding, periodic table trends, and chemical properties of elements.
Focus on distinguishing different types of hydrides; practice the industrial preparation and reactions of hydrogen peroxide and water.
Solve 20-30 problems, focusing on hydrogen bonding, hydrides, and properties of hydrogen.
