The history of the atomic structure and quantum mechanics dates back to the times of Democritus, the man who first proposed that matter is composed of atoms. These theories could not gain much importance due to the lack of technology. The experiments conducted during the nineteenth century and early twentieth century revealed that even atom […]
Linear Combination Of Atomic Orbitals...
What is Linear combination of atomic orbitals Linear combination of atomic orbitals which is also known as LCAO is an approximate method for representing molecular orbitals. It’s more of a superimposition method where constructive interference of two atomic wave function produces a bonding molecular orbital whereas destructive interference produces non-bonding molecular orbital. Conditions for Linear combination of […]

Chemical Change: Reversible And Irrev...
What is a chemical change Changes are very random or an uncertain phenomenon, it can be better or worse depending on your view. Every day we see different objects changing around us like melting of ice, cooking of food etc. In some cases, you get back the original substance and in some, you won’t get […]
Antihistamine – Treatment for Allergi...
What is Antihistamine? Antihistamine is a class of drugs that inhibit the physiological action of histamines. Histamine is an organic compound, which is involved in local immune responses and also acts as a neurotransmitter. It is also involved in the inflammatory response and is a mediator of pruritus. Histamine is produced by basophils and is […]
Aspartic Acid
Aspartic acid is also called as aspartate amino acids that needed for the biosynthesis of proteins. It is one of the two acidic amino acids. It consists a α-carboxylic acid group, α-amino groups, and CH2 COOH side chain. Aspartic Acid Formula The formula for aspartic acid is: C4H7NO4 Aspartic Acid Structure It was first discovered […]
Elementary Idea of Antioxidants
What are Antioxidants? Substances that inhibit the oxidation of other molecules are called antioxidants. Free radicals are produced as a result of oxidation and these free radicals trigger a chain of chemical reactions that damage the cells. These chain reactions can be terminated by using some antioxidants such as ascorbic acid and thiols. A complex […]
How do Antibiotics Help Humans Fight ...
What are Antibiotics Antibiotics are medicines that are used to treat as well as prevent bacterial infections. It inhibits the growth and sometimes destroys the microorganisms that cause infections. Its use is encouraged because it is fairly harmless to human beings and animals. It treats diseases caused by bacteria by inhibiting the synthesis of their […]

Carbon Tetrachloride Uses and Its Eff...
Carbon Tetrachloride Organic compounds that have a halogen group element as a functional group are called haloalkanes or haloarenes depending on the structure of the compounds. If it is an aliphatic compound it is called haloalkane and if the compound is aromatic then it is referred to as haloarenes. Those compounds that have two or […]
