Haloalkanes and Haloarenes. Haloalkanes: Nomenclature, nature of C-X bond, physical and chemical properties, mechanism of substitution reactions, optical rotation. Alchohols, Phenols and Ethers. Alcohols: Nomenclature, methods of preparation, physical and chemical properties of primary alcohols only , identification of primary, secondary and tertiary alcohols, mechanism of dehydration, uses with special reference to methanol and ethanol.
These halogen ions, due to their strong electronegativity, replace the hydrogen atoms in organic molecules and form such compounds. The 12th NCERT chemistry PDF also mentions how the halogen atoms attach to the sp 3 hybridised carbon in alkyl groups, while for aryl groups, they do so with the sp 2 hybridized carbon. Such compounds are of particular importance and used in various ways in our day to day lives. One of the key topics in organic chemistry, alcohols and phenols are formed when an -OH group, respectively replace hydrogen atoms in aliphatic and aromatic hydrocarbons.
Alcohols and phenols find extensive usage in our daily lives and is a major constituent inside the food we eat. Ethers are compounds where the hydrogen atoms are replaced by an alkoxy R-O or aryloxy Ar-O group.
Ethers are used in making fragrances. When carbon and hydrogen are attached to the carbonyl group, they are called aldehydes. If two carbon atoms bond with the group, they are known as ketones. And if the group bonds with an -OH group, it is called carboxylic acid. Like other organic compounds discussed before, amines are those compounds in which the hydrogen atoms in the ammonia NH 3 molecule are replaced by alkyl or aryl groups.
Proteins and amino acids, which help in the intricate functioning of our muscles and other body parts, are all derivates of amines. Amines contain a nitrogen atom and another lone pair of electrons. The functional group -NH 2 is called the amino group. Even though biology and chemistry are different academic subjects, human bodies are the fusion of both of them.
We have thousands of different atoms and molecules inside our body, without which we cannot function. The study of how chemicals shape and help in the efficient working of human bodies is called biochemistry.
The most essential biomolecules inside our bodies are carbohydrates, proteins, fats and hormones. Polymers make up almost every tangible product which we use in our day to day lives. The most important polymer, plastic, is one of the most widely used product nowadays.
If we look inside polymer molecules, we will notice repeating units called monomers, which are bound together with the help of covalent bonds. Due to this repeating structure, polymers are macromolecules, with huge molecular mass. Combining all the above chapters, in the end, students should not only see these as formulas, and reactions which they have to perform in laboratories and write on exam papers, but have a holistic idea of how each of the chapters plays a significant role in forming the world what we see today, everything inside and around us.
