Bulk Preparation of Dihydrogen by Electrolytic Method: In the electrolytic method, water (H2OH2O) is electrolyzed using a suitable electrolyte (such as potassium hydroxide (KOHKOH) or sulfuric acid (H2SO4H2SO4)) and applying an electric current. The role of the electrolyte is to provide ions that can conduct electricity and facilitate the flow of current through the solution. During electrolysis, water molecules are reduced at the cathode to form hydrogen gas (H2H2) and oxidized at the anode to form oxygen gas (O2O2).

Consequences of High Enthalpy of H-H Bond: The high enthalpy of the H-H bond (436 kJ/mol436kJ/mol) in dihydrogen makes it relatively inert and unreactive under standard conditions. This high bond energy results in a low tendency for hydrogen gas to undergo chemical reactions, particularly with other nonmetals. As a result, dihydrogen is primarily used as a fuel or reducing agent in industrial processes.

Characteristics of Electron-Deficient Hydrides: Electron-deficient hydrides typically have an incomplete octet or share fewer electrons than expected in their bonding arrangements. As a result, they often exhibit high reactivity and can act as Lewis acids by accepting electron pairs from Lewis bases. Their structures often involve electron-deficient atoms surrounded by electron-rich regions, leading to polar or ionic bonding interactions. Examples include boranes and aluminum hydrides.

Carbon Hydrides (Alkanes): The general formula for alkanes is CnH2n+2CnH2n+2. These compounds are predominantly nonpolar and do not possess any functional groups that can donate or accept electrons easily. Therefore, they are not expected to act as Lewis acids or bases under normal conditions. However, under certain conditions, they might exhibit weak Lewis acid-base interactions, but this behavior is not significant compared to other functional groups like carbonyl groups or acidic hydrogen atoms.

Non-Stoichiometric Hydrides: Non-stoichiometric hydrides are compounds that do not adhere to fixed stoichiometric ratios between the metal and hydrogen atoms. They often exhibit variable compositions and properties due to defects or vacancies in their crystal structures. Alkali metals, being highly reactive, are not typically found in non-stoichiometric hydrides. Non-stoichiometric hydrides are more commonly associated with transition metals or metalloids due to their ability to form complex structures with variable oxidation states.
