    Question:33

    Give reasons:
    (i) Lakes freeze from the top towards the bottom.
    (ii) Ice floats on water.

    Answer:

    1. The lake freezes from top to bottom because the temperature during winter keeps on decreasing, and the movement of water happens in such a way that the cold water is heavier and so it sinks to the bottom. While warm water replaces it by coming on the surface. The process repeats until the temperature decreases below 4 degrees and the lake keep on freezing from top to bottom.

    2. Density of ice is less than water due to its structure which forms empty spaces between the water molecules, 4 atoms of Hydrogen surround 1 of oxygen, and therefore make ice float on water

    Question:34

    What do you understand by the term ‘auto protolysis' of water? What is its significance?
    Answer:

    Autoprotolysis is the process when two similar molecules react with each other to produce products that are called ions with Proton transfer. Autoprotolysis of water means the transfer of one Proton from a certain molecule to another. This explains the ability of water act as both acid and base. Therefore, making it amphoteric in nature.
    H_2O (l) + H_2O (l) \overset{reversible}{\rightarrow} H_{3}O^{+} (aq) + OH^{-} (aq)

    Question:35

    Discuss briefly de-mineralisation of water by ion exchange resin.
    Answer:

    Demineralization of water means that all the soluble salts present in water are removed through cation and anion exchange. In the cation exchange process, cations of sodium, calcium and magnesium replace those of Hydrogen. While the anion exchange process exchanges OH. This both combine to produce water.
    H^{+} + OH^{-} \rightarrow H_{2}O

    Question:36

    Molecular hydrides are classified as electron-deficient, electron precise and electron-rich compounds. Explain each type with two examples.
    Answer:

    There are three major types of molecular hydrides.
    Electron precise hydrides are the ones that have just enough exact number of electrons to facilitate normal covalent bonds. These are the hydrides which are primarily comprised of group 14 elements: CH_{4}.
    Electron deficient hydrides are the ones which do not possess enough number of electrons to facilitate normal covalent bonds. Hydrides of group 13 a prime examples; B_2H_6.
    Electron rich hydrides are ones which have an excess number of electrons remaining after normal covalent bonds. Elements of group 15 16 17 are prime examples; NH_3.

    Answer:

    The given properties such as boiling point, enthalpy of vaporization and viscosity are all dependent on the intermolecular forces of the liquids. Water has a lower intermolecular force of attraction as compared to D_{2}O , and thus the values are lower for water.

    Question:42

    Dihydrogen reacts with dioxygen (O_{2}) to form water. Write the name and formula of the product when the isotope of Hydrogen, which has one proton and one neutron in its nucleus is treated with oxygen. Will the reactivity of both the isotopes be the same towards oxygen? Justify your answer.
    Answer:

    Deuterium (D) is the isotope of Hydrogen which contains one proton and one neutron. Thus, on the reaction of water with deuterium, heavy water (deuterium oxide) is produced. Deuterium’s bond is stronger than the normal hydrogen bond, and thus H_{2} reacts more with deuterium than oxygen.

    2D_{2} + O_{2} \rightarrow (heat) 2D_{2}O

    Question:43

    Explain why HCl is a gas and HF is a liquid.
    Answer:

    F is a stronger electronegative than chlorine, and so forms a stronger bond with Hydrogen than chlorine. In order to break HF bonds, more energy is required as compared to break HCl bonds. This is the reason why HF has a higher boiling point than HCl and is a liquid at room temperature.

    Question:44

    When the first element of the periodic table is treated with dioxygen, it gives a compound whose solid-state floats on its liquid state. This compound has an ability to act as an acid as well as a base. What products will be formed when this compound undergoes autoionisation ?
    Answer:

    The first element is Hydrogen, and its molecular form is dihydrogen, so when it reacts with oxygen, it forms water, which is physical solid-state is ice and has a density lower than water, so it floats on water. Water has an amphoteric nature which acts as a base went around acids and vice versa.
    H_{2}O (as\;an\; acid) + NH_{3} \rightarrow NH4^{+} + OH^{-} (aq)
    H_{2}O (as \;a\; base) + H_2S \rightarrow H_{3}O^{+} + HS^{-}

    Question:46

    Give reasons why Hydrogen resembles alkali metals?
    Answer:

    Hydrogen has a specific unique electronic configuration which is similar to alkali metals but belongs to group 1 in the periodic table. Its strong nature like the alkali metals due to its configuration makes it give one electron to combine to form unipositive ions.

    Question:47

    Hydrogen generally forms covalent compounds. Give reason.
    Answer:

    Due to its configuration, Hydrogen also resembles certain halogens, given its ionization enthalpy. Therefore, when acting as a halogen, it forms hydrides by combining with the elements to form a diatomic molecule along with covalent compounds.

    Question:48

    Why is the ionisation enthalpy of Hydrogen higher than that of sodium?
    Answer:

    Hydrogen has a higher ionization enthalpy than sodium because sodium has a different configuration that is in the last shell, the electron is in 3s, which if lost, the configuration resembles neon, which is the noble gas. However, with Hydrogen, the case is different, and the electron is in the 1s orbital which on losing doenot amount to attainement of noble gas configuation.

    Question:49

    The basic principle of a hydrogen economy is transportation and storage of energy in the form of liquid or gaseous Hydrogen. Which property of Hydrogen may be useful for this purpose? Support your answer with the chemical equation if required.

    H2O2 + Cl2\rightarrow 2HCl + O2

    Question:53

    With the help of suitable examples, explain the property of H_{2}O_{2} that is responsible for its bleaching action?
    Answer:

    H_{2}O_{2} serves as a great bleaching agent and disinfectant, commercially sold as perhydrol and disintegrates on exposure to direct light.
    The bleaching action of H2O2 is due to labile oxygen which it releases on decomposition.
    H2O2 → H2O+[O]
    The nascent oxygen combines with coloured material and makes it colourless. It can bleach feather, silk, wool, paper, etc.

    Question:54

    Why is water molecule polar?
    Answer:

    The polar nature of the water molecule is due to the structure of the bent molecule and bond length of 95.7pm and the angle of 104.5.

    Question:55

    Why does the water show a high boiling point as compared to hydrogen sulfide? Give reasons for your answer.
    Answer:

    Water has a higher boiling point than hydrogen sulfide because the hydrogen bonding in water is quite different, and hydrogen sulfide does not have hydrogen bonding at all.

    Question:56

    Why can dilute solutions of hydrogen peroxide not be concentrated by heating? How can a concentrated solution of hydrogen peroxide be obtained?
    Answer:

    Hydrogen peroxide causes burns when it is heated, so it should not be concentrated. You should use other methods other than heating to make it concentrated, such as distillation with water under pressure. Further distillation under pressure and careful extraction can give you pure hydrogen peroxide.

    Question:57

    Why is hydrogen peroxide stored in wax-lined bottles?
    Answer:

    Hydrogen peroxide is highly reactive, and that is stored in dark coloured bottles because it disintegrates on exposure to direct light.
    2 H_{2}O_{2} \rightarrow 2 H_{2}O + O_{2}

    Question:58

    Why does hard water not form lather with soap?
