Science > Chemistry > Chemical Kinetics > Molecularity of Reaction and Catalysis In this article, we shall study the molecularity of reaction and catalysis. The Concept of Elementary Reactions: Many reactions that follow a simple rate law are actually taking place in series of steps. These reactions are called complex reactions. Each step in a […]

Concept of Hydrolysis

Science > Chemistry > Physical Chemistry > Ionic Equilibria > Concept of Hydrolysis In this article, we shall study the concept of hydrolysis. Before studying the concept we have to understand different types of salts. Types of salts: Salts are classified on the basis of the nature of the acids and bases from which they […]

1 Comment on Bonding in Organic Compounds

Generally, organic compounds are formed by covalent bonds among the constituent atoms. Carbon is tetravalent. It contains four electrons in its valence shell. One carbon can share its valence electrons with other elements or with another carbon to form the covalent bonds. Methane is the simplest organic compound. One carbon atom shares its four electrons […]

Coordination Compounds

In this article, we shall study the coordination compounds, their terminology, and nomenclature Double Salts: These are the addition molecular compounds which are stable in the solid-state but dissociate into constituent ions in the solution. They are simply a combination of two different salts. e.g., Mohr’S salt, [FeSO4·(NH4)2SO4. 6H2O gets dissociated into Fe2+, NH+4, and SO2-4 ions. […]

Science > Chemistry > Biomolecules > Proteins and Their Classification The name protein (proteios Greek = pre-eminent or first) was first suggested, in 1838, by a Swedish chemist Berzelius to a Dutch chemist Mulder, who referred it to the complex organic nitrogenous substances found in the cells of the living beings. They are naturally occurring nitrogenous polymers of different alpha-amino […]

In this article, we shall study the types of chemical reactions. Before understanding the types of chemical reactions, let us study the meaning of the terms “a physical change” and “a chemical change” Physical Change: A change in which only the physical properties of a substance are changed is called a physical change. In a […]

No Comments on Formation of Differential Equations – 01 (Single Arbitrary Constant)

In this article, we shall study to form a differential equation by eliminating a single arbitrary constant from the given relation. Example – 01: xy = c Solution: Given xy = c ……….. (1) Differentiating both sides w.r.t. x x + y(1) = 0 ∴ x + y = 0 This is the required differential Equation […]
