NCERT Solutions for Class 11 Chemistry Chapter 9 Hydrogen- Exercise Questions
Question 9.1 Justify the position of hydrogen in the periodic table on the basis of its electronic configuration
Answer :
Answer-The electronic configuration of the H atom is . Due to the presence of only one electron, it exhibits dual behaviour,i.e., it resembles both alkali metals of group 1 and also along with the halogens of group 17.
It can lose one electron to form a unipositive ion. Both H and alkali metals form monovalent cations by losing one electron from its outer shell. Both alkali and hydrogen shows +1 oxidation numbers.both have an affinity towards electronegative elements and readily combine with them and forms oxide, halides, and sulphides.
It has a very high ionization enthalpy and does not possess metallic characteristics under normal conditions. In fact, in terms of ionization enthalpy, hydrogen resembles more with halogens, ionization enthalpy of Li is 520 kJ mol–1, F is 1680 kJ mol–1 and that of H is 1312 kJ mol–1. Like halogens, it forms a diatomic molecule, combines with elements to form hydrides and a large number of covalent compounds.
Question 9.2 Write the names of isotopes of hydrogen. What is the mass ratio of these isotopes ?
Answer :
Isotopes of Hydrogen are-
The mass ratio is 1:2:3
Question 9.3 Why does hydrogen occur in a diatomic form rather than in a monoatomic form under normal conditions ?
Answer :
Ionisation enthalpy of hydrogen is quite high(1312 kJ/mol). Hence it is very difficult to remove its only one electron. As a result, the tendency to exist in the monoatomic form is very low.
Question 9.4 How can the production of dihydrogen, obtained from ‘coal gasification’, be increased?
Answer :
The process of producing syngas from coal is known as 'coal gasification'
The production of dihydrogen can be increased by reacting carbon monoxide of syngas mixture with the steam in the presence of iron chromate as a catalyst. This is called 'water gas shift reaction '. carbon dioxide can be removed by scrubbing with a sodium solution.
Answer :
The dihydrogen is prepared by electrolysis of acidified water using platinum electrodes. generally acid is sulphuric acid and base is sodium hydroxide is used.
Role of electrolyte-
The electrical conductivity of pure water is very low due to the absence of ions in it. Hence electrolysis of water takes place at slow rate. If we add an electrolyte as an acid or base it will increase the rate of electrolysis. Electrolytes provide ions in this process for the better conduction of electricity.
Question 9.7 Discuss the consequences of high enthalpy of H–H bond in terms of chemical reactivity of dihydrogen?
Answer :
The ionization enthalpy of the H-H bond is very high (1312kJ/mol). It means hydrogen has less tendency to form ions. Its ionization enthalpy is comparable to halogens. Hence it forms a diatomic molecule, hydrides with the elements, and a large number of covalent bonds. It does not possess any metallic character like metals
Answer :
(i)Electron-deficient hydrides-
Those compounds having fewer electrons to writing its conventional Lewis structure. examples (all the elements of group 13 form electron deficient hydrides)
(ii)Electron-precise hydrides-
Those compounds have the required number of electrons to write their conventional Lewis structure. ex- (all elements of group 14 form such compounds)
(iii)Electron-rich hydrides-
Electron-rich hydrides have excess electrons which are present as lone pairs. elements of group 15-17 form such compounds like has one lone pair and two lone pair respectively.
Answer :
Electron-deficient hydrides do not have required electrons to form a regular bond in which two electrons are shared by two atoms. e.g. etc
Because of electron deficiency, they have the tendency to accept electrons. hence they act as Lewis acid.
Question 9.10 Do you expect the carbon hydrides of the type (CnH2n + 2) to act as ‘Lewis’ acid or base? Justify your answer.
Answer :
the general term
for n = 1, 2, 3.. we get ...
Lewis acids are an electron acceptor, So the above compound should be electron deficient species.
taking an example
Here we can directly count that both the Carbon atom has perfect 8 electrons in sharing. they follow the octet rule. It is electron precise hydride and it neither donate or accept electrons to act Lewis acid or base
Answer :
Non-stoichiometric hydrides are hydrogen deficient compounds. they are formed by d & f block elements. Such hydrides do not follow the law of constant composition.
Examples- etc.
Alkali metals do not form these types of hydrides. Alkali metals form stoichiometric hydrides. These hydrides are ionic in nature.
Question 9.12 How do you expect the metallic hydrides to be useful for hydrogen storage? Explain
Answer :
Metallic hydrides are hydrogen deficient and they don't hold the law of constant composition.it is established that hydrides of nickel, palladium, and Ce have lattice different where hydrogen occupies the interstitial position in the lattices allowing further absorption of hydrogen on these metals. Some of the metals like Pd and Pt accommodate a very large volume of hydrogen and therefore, can be used for hydrogen storage.
Question 9.13 How does the atomic hydrogen or oxy-hydrogen torch function for cutting and welding purposes? Explain.
Answer :
Atomic hydrogen can be prepared by dissociation of a bond of dihydrogen with the help of an electric arc. This release a huge amount of energy around 135 kJ/mol and this energy can be used to generate a high temperature of 4000K, which is desirable for welding and cutting of metals. Therefore, atomic hydrogen or oxy-hydrogen torch are used for welding purpose.
Question 9.14 Among NH3, H2O and HF, which would you expect to have highest magnitude of hydrogen bonding and why?
Answer :
The strength of hydrogen bonding depends on the electronegativity of an atom
electronegativity order
The expected order should be
But the actual order is
This is because of the extent of H bonding in a water molecule is more due to the presence of one extra hydrogen atom. Also, Oxygen atom forms a huge ring like structure through its high ability of hydrogen bonding
Answer :
Saline hydrides are known to react with water violently and produce fire.
this is the general reaction formula. We see that the product is a base and hydrogen gas.
