    Alkali metals are highly reactive in nature due to low ionization enthalpy andstrong electropositive character. They do not occur in free state and are always combined with other elements.

    Oxidation and Reduction: Redox Reactions

    Oxidation and reduction reactions occur simultaneously. When oxidation occurs in one substance, reduction takes place in the other substance. Such reactions are called redox reactions. In the name ‘redox’, the term ‘red’ stands for reduction and ‘ox’ stands for oxidation.

    CuO + H2 → Cu + H2O

     Fe3O4 + 4H2 → 3Fe + 4H2O

    In both, the above reactions, oxidation and reduction occur simultaneously. One of the reactants acts as an oxidising agent and gets reduced, while the other acts as a reducing agent and gets oxidised.

    The (CH3) 3C+ is more stable because it is a 3°(Tertiary) Carbocation. So it has more presence of electron releasing group as compared to the (CH3) 2CH, which is a 2°(Secondary) carbocation. Amd we know that Tertiary carbocation is more stable than secondary.

    Due to its smaller size and unavailability of d-electrons boron is found to exhibit properties which are in contrast to the other elements of the boron family. These properties are known as anomalous properties of boron. Some of these anomalous properties are discussed below.

    1. Except for boron, the compounds of the elements of the boron family like tetrahedral [M(OH)4]– and octahedral [M(H2O)6]3+ (where M denotes the member of boron family) exists in an aqueous medium.
    2. The maximum covalence of boron is 4 due to the absence of d orbitals.
    3. Boron is a metalloid while the rest of the family are post transition metals.
    4. The boron oxides and hydroxides are acidic in nature, whereas the other elements in the family form oxides and hydroxides which are amphoteric in nature.

    Borax acid is formed when it is acidified.

    Na2B4O7  + 2HCl + 5H2O → 2NaCl + 4H3BO3

    Borax is a weak acid so it is slightly hydrolyzed in solution and is alkaline in nature.

    B2O72- + 7H2O →2OH- + 4H3BO3

    When heated, borax undergoes various transitions. It first loses water molecules and swells. Then, it turns into a transparent liquid, solidifying to form a glass-like material called borax bead.

    The Born–Haber cycle is an approach to analyze reaction energies. ... The lattice enthalpy is the enthalpy change involved in the formation of an ionic compound from gaseous ions (an exothermic process), or sometimes defined as the energy to break the ionic compound into gaseous ions (an endothermic process).
