    Tautomers are isomers of a compound which differ only in the position of the protons and electrons. The carbon skeleton of the compound is unchanged. A reaction which involves simple proton transfer in an intramolecular fashion is called a tautomerism.

    Uncertainty principle, also called Heisenberg uncertainty principle or indeterminacy principle, statement, articulated (1927) by the German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory. The very concepts of exact position and exact velocity together, in fact, have no meaning in nature.

    • This principle was in favor of the wave nature of matter
    • It stated that it is impossible to simultaneously evaluate the precise position and momentum of particle. There is always some probability in predicting the position and momentum of a particle. Mathematically, it can be written as:

      (Δx)(Δp) ≥ h/(2π)

    The terms h​eterogeneous and homogeneous refer to mixtures of materials in chemistry.
    Homogeneous equilibrium: When in an equilibrium reaction, all the reactants and the products are present in the same phase , it is called homogeneous equilibrium.
    Heterogeneous equilibrium : When in an equilibrium reaction, all the reactants and the products are present in two or more than two phases , it is called heterogeneous equilibrium.

    Those mixtures in which the substances are completely mixed together and are indistinguishable from one another is called homogenous mixture. They have uniform composition throughout its mass. For Ex: Sugar solution,Salt solution,Alcohol and water,Soft drinks etc.

    Hypophosphorous acid is a phosphorus oxyacid and a powerful reducing agent with molecular formula H3PO2. It is a colorless high-melting compound, which is soluble in water, dioxane, and alcohols. The formula for blue acid is generally written H3PO2, but a more descriptive presentation is HOP(O)H2 which highlights its monoprotic character.

    Ortho is more acidic than para because of negative inductive as well as negative resonance effect are operated by no2 in Ortho nitro phenol. Also when no2 is on para position, there is a lot of distance between OH and NO2, so only negative inductive effect operates.

    Lithium is strongest Reducing agent because of lowest standard reduction potential. When something is oxidized, it reduces another substance, becoming a reducing agent. Hence lithium is the strongest reducing agent.

    Fajans' rule states that a compound with low positive charge, large cation and small anion has ionic bond where as a compound with high positive charge, small cation and large anion are covalently bonded. NaCl is correctly predicted to be ionic since Na+ is a larger ion with a low charge and Cl− is a smaller anion.

    There are 2 statements of second law of thermodynamics given by two scientists:

    • Kelvin-Planck ∫Statement: - No process is possible whose result is the absorption of heat from a reservoir and the complete conversion of the heat into work.
    • Clausius statement: - No process is possible whose result is the transfer of heat from a colder object to a hotter object.

    Explanation of Kelvin-Planck Statement: It is always impossible that the total amount of heat which is supplied to system will get converted to work, and there will always be loss of heat. Complete conversion of heat into work is not possible.

    Explanation of Clausius statement: - Transfer of heat from colder body to hotter body won’t take place until some external work is done on the system.
