    • In 1864, Newlands arranged the known 56 elements in the order of increasing atomic masses.
    • He observed that the properties of every eighth element are similar to the properties of the first element.
    • Based on this observation, he proposed the Law of Octaves for the classification of elements.

    Law of Octaves: When the elements are arranged in the increasing order of their atomic masses, the properties of every eighth element are similar to the first.

    branched alkanes have weaker van der waals forces because of the smaller area of contact between the molecules. so less energy is needed to overcome the intermolecular force. Linear alkanes can line up more closer and therefore have stronger van der waals forces than unbranched alkanes. so just remember that van der waals forces are stronger when there is more area of contact between molecules, and obviously area of contact is smaller in branched molecules compared to linear molecules (when they both have the same molecular formula).

    1Thank You

    Rishabh Rathi 6 years, 11 months ago

    It's because when we observed the boiling point of alkane and branched we find that branched has low boiling point which means vanderwaal force is less. That's all i know May be it is due to the open chain has large area and no. of molecules which would add van der waal force. Hope this would help.

    The oxide which shows both acidic and basic nature when reacted with acids and base. Eg Al2O3. Al2O3 + HCl ----> AlCl3 + H2O Al2O3 + NaOH ---->NaAlO2 + H2O In first reaction amphoteric oxide is reacted with acid in which it forms a salt and water. Similarly in second reaction it is reacted with a base in which it forms salt and water.

    Oxides of metals which have both acidic as well as basic behaviour are known as amphoteric oxides Example:- Acidic medium :-Al2O3+6HCl---> 2AlCl3+3H2O Basic medium :- Al2CO3+2NaOH---> 2NaAlO2+H2O

    Oxidation number refers to the oxidation state of a particular element in a compound by following a set of rules. The rules were set on the basis of the electron pair of a covalent compound and the electronegativity of an element.

    The Maxwell-Boltzmann equation, which forms the basis of the kinetic theory of gases, defines the distribution of speeds for a gas at a certain temperature. From this distribution function, the most probable speed, the average speed, and the root-mean-square speed can be derived.

    Significance / Importance of Boyle's Law. According to Boyle's law, at constant temperature the density of gas is directly proportional to pressure. This is because density depends on volume, smaller the volume higher the density. So when pressure is applied, volume is reduced i.e. density is increased.
