    Swarts reaction is generally used to get alkyl fluorides from alkyl chlorides or alkyl bromides. This is done by heating of the alkyl chloride/bromide in the presence of the fluoride of some heavy metals ( silver fluoride or mercurous fluoride for example). The reaction will proceed if sodium fluoride or potassium fluoride is used, but the resulting yield will be significantly lower. This process was first reported by Frederic Jean Edmond Swarts in 1892.

    Osmotic pressure is a pressure which is occur in equilibrium at the soln side exerts pressure to stop the osmosis is called osmotic pressure which is depend upon molarity and its formula is pi equal to mrt where m is is molarity and r is constant and t is temperature in kelvin.

    colligative property depend on the number of solute particles irrespective of their nature relative to the total number of particles present in the solution.Osmotic pressure depends upon the number of particles of solute, i.e., molarity of solute. Therefore, it is considered as colligative property.

    Above answer is right but the point tobe added is water supports incombustion while its constituents don't is just because the properties of ionic compounds are different from their constituent elements. ?

    Boyle's law is the law which gives relation between pressure and volume of fixed mass of a gas at constant temperature . Boyle's law: " At constant temperature , Pressure is inversely proportional to Volume of fixed mass of a gas " .

    0Thank You

    Yogita Ingle 5 years, 9 months ago

    Boyle’s law is a gas law which states that the pressure exerted by a gas (of a given mass, kept at a constant temperature) is inversely proportional to the volume occupied by it. In other words, the pressure and volume of a gas are inversely proportional to each other as long as the temperature and the quantity of gas are kept constant.

    Molar mass of O3 will be 16 x3 =48 g .

    Here 16g 0f O3 is given so no of moles of O3 will be 16 ÷48 = 1/3 mole .

    now 1 mole = 3 ×6.022 ×{10^23} oxygen atoms therefore 1/3 mole =6.022 ×1/3×3 ×{10 ^23} no of atoms.

    O3 is Ozone molecule which contain 3 Oxygen atoms.

    Chemicals involved in the reaction are Aluminium turnings, anhydrous tertiary butyl alcohol, 1% Mercury oxide , Benzene ( as solvent).

    Al  +  3 t-BuOH   -----> Al (0-t-Bu)3

    [in the presence of heat and Hg2Cl2 in benzene as catalyst]

    When aluminium turnings are heated with tertiary butyl alcohol, in the presence of mercury oxide in benzene solvent, Aluminum tertiary butoxide is formed.

    Werner’s theory

    According to the theory the postulates are:

    1. Metal exhibit 2 types of vacancies: primary valency and secondary valency
    2. Primary valency gives the information about oxidation state and secondary valency gives the information about coordination number
    3. Primary valency is variable whereas secondary valency is always fixed
    4. Secondary valency that is coordination number determines the geometry of molecule or we can say polyhedral of the molecule.
    5. Metal stabilize all its vacancies

    • Osmosis influences the transport of nutrients and the release of metabolic waste products.

    • It is responsible for the absorption of water from the soil and conducting it to the upper parts of the plant through the xylem.

    • It stabilizes the internal environment of a living organism by maintaining the balance between water and intercellular fluid levels.

    • It maintains the turgidity of cells.

    • It is a process by which plants maintain their water content despite the constant water loss due to transpiration.

    • This process controls the cell to cell diffusion of water.

    • Osmosis induces cell turgor which regulates the movement of plants and plant parts.

    • Osmosis also controls the dehiscence of fruits and sporangia.

    • Higher osmotic pressure protects the plants against drought injury.
