NCERT Solutions for Class 12 Chemistry Chapter 5: Surface Chemistry

Surface chemistry is the branch of chemistry, that deals with the study of phenomena occurring at the surface separating the two bulk phases. These two bulk phases can be pure compounds or solutions.

Adsorption: The phenomenon of attracting and retaining the molecules of the substance on the surface of a liquid or a solid resulting in a higher concentration of molecules on the surface is called adsorption. The substance thus adsorbed on the surface is called the adsorbate and the substance on which it is adsorbed is called adsorbent. The reverse process, i.e. removal of the adsorbed substance from the surface is called desorption (which can be brought about by heating or reducing the pressure). The adsorption of gases on the surface of metals is called occlusion.

NCERT Solutions for Class 12 Chemistry Chapter 6: General Principles and Processes of Isolation of Elements

The whole process of obtaining a pure metal from one of its ores is known as metallurgy. To extract the metal from ores, several physical and chemical methods are used. The method used depends upon the nature of the ore, the properties of the metal, and the local conditions. Thus, it is not possible to have a universal method for the extraction of all the metals from their ores. However, the metallurgy of a metal involves three main operations:

1. Concentration or Dressing
2. Reduction
3. Purification or Refining

NCERT Solutions for Class 12 Chemistry Chapter 7: The p-Block Elements

The chapters covered in these sections are

• Elements of group 13 are called the Boron family (₅B, ₁₃Al, ₃₁Ga, ₄₉In, ₈₁Tl, ₁₁₃Uut).
• Elements of group 14 are called the Carbon family (₈C, ₁₄Si, ₃₂Ge, ₅₀Sn, ₈₂Pb, ₁₁₅Uup).
• Elements of group 15 are called the Nitrogen family (₇N, ₁₅P, ₃₃As, ₅₁Sb, ₈₃Bi).

• Elements of group 17 are called Halogens (₉F, ₁₇Cl, ₃₅Br, ₅₃I, ₈₅At).
• Elements of group 18 are called Noble gases (₂He, ₁₀Ne, ₁₈Ar, ₃₆Kr, ₅₄Xe, ₈₆Rn).

NCERT Solutions for Class 12 Chemistry Chapter 8: The d & f Block Elements

In the periodic table, the block elements are placed between block and block elements. These are called transition elements because they show a gradual gradation in periodic properties. The transition elements are mainly those elements that either in the atomic or ionic state contain partially filled subshells. It must be noted that the elements of group 12 (Zn, Cd, and Hg) have filled subshells in atomic as well as ionic form, so they do not truly represent transition elements. Moreover, they also do not exhibit general properties of transition elements like variable oxidation states, coloured compounds, formation of complex compounds etc. However, they are studied with transition elements just to maintain the status of the periodic table. Further, it must be noted that the elements of group 3 (Sc, Y, La and Ac) differ in their properties from those of other transition elements (they are uniformly trivalent, diamagnetic and colourless).

NCERT Solutions for Class 12 Chemistry Chapter 9: Coordination Compounds

Transition metal ions have a great tendency to form complexes with other molecules or ions (which can donate a pair of electrons to form a coordinate bond) called ligands. This property of formation of complexes is due to vacant d-orbitals (which can accept electron pair) and high nuclear charge with small size which facilitates the acceptance of electrons from the ligands. The complexes of transition elements of small size are more stable as compared to those of large size elements in a particular series with the same oxidation state. If the oxidation state is different for the same metal, then the complex with a greater oxidation state of central metal will be more stable.

NCERT Solutions for Class 12 Chapter 10: Haloalkanes and Haloarenes

This chapter is the first chapter of organic chemistry in class 12 chemistry and you are going to cover several important reaction mechanisms in this chapter like SN reaction and its use.

NCERT Solutions for Class 12 Chapter 11: Alcohols, Phenols, and Ethers

If it is asked you to pick up ten aliphatic compounds and with them to be stranded on a desert island, you choose only alcohols. Why – because you could make nearly every other kind of aliphatic compound from them and a host of others. On your desert island, you would use your alcohols not only as raw material but also as a solvent in which the reactions are carried out and the products are recrystallized. Not only this if you are tired after a day-long experiment get refreshed with (isopropyl) alcohol rub and perhaps relax over a cool (ethyl) alcoholic drink.

NCERT Solutions for Class 12 Chemistry Chapter 12: Aldehydes, Ketones, and Carboxylic Acids

Aldehydes and ketones are the compounds containing a carbonyl group, >C=O, in which a carbon atom is linked to an oxygen atom by a double bond. They have the same general formula C_nH_2nO. The general structure of aldehydes and that of ketones is where R and R¢ may be the same or different. Formaldehyde represents the simplest aldehyde in which the carbonyl group is attached to two hydrogen atoms, i.e., Formaldehyde is exceptional in that the carbonyl group carries two hydrogen atoms and no alkyl substituents. It is, therefore, not surprising that it displays characteristic properties.

NCERT Solutions for Class 12 Chemistry Chapter 13: Amines

Amines play a vital role in medicinal chemistry. As our body is having a lot of amino acids, these amines help in the regulation of our body. It is also believed that vitamins were named keeping vital amines in mind (though many vitamins don't have nitrogen at all). Similarly, to produce several synthetic dyes, and pigments amines are used. Therefore, the amines are very important in our everyday life. Let us see how this is.

NCERT Solutions for Class 12 Chemistry Chapter 14: Biomolecules

Carbohydrates (hydrates of carbon) are naturally occurring organic compounds having the general formula C_x(H₂O)_y, which are constantly produced and assimilated in nature and take part in many important biochemical reactions. However, several compounds having general formulas such as that of carbohydrates have been synthesized. There are many compounds, which are carbohydrates by chemical behaviour but do not conform to the general formula. For example, 2-deoxyribose, C₅H₁₀O₄ is a carbohydrate by chemical reaction but does not conform to the general formula. All the carbohydrates are optically active. So, carbohydrates are now defined as the polyhydroxy carbonyl compounds, which give polyhydroxy carbonyl compounds on hydrolysis. Carbohydrates are polyhydroxy aldehydes or ketones that have an OH bonded to each of the carbon other than the C=O group. 

NCERT Solutions for Class 12 Chemistry Chapter 15: Polymers

Polymers are compounds of very high molecular masses formed by the combination of a large number of simple molecules. The simple molecules which combine to give polymers are called monomers. The process by which the simple molecule (i.e. monomers) are converted into polymers is called polymerization.

Example: Polyethylene. All polymers are macromolecules, but all macromolecules are not polymers because polymers consist of repeating units of monomer e.g., chlorophyll is a macromolecule but not a polymer.

Chapter 16: Chemistry in Everyday Life

Learn the fundaments to chemistry which you use in daily life, it is again an important chapter of class 12 chemistry.
