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 […]
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 […]
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 […]
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 […]
In this article, we shall find the maximum and minimum value of the given function. Example – 01: If x + y = 3 show that the maximum value of x2 y is 4 Solution: Given x + y = 3 hence y = 3 – x ∴ x2 y = x2(3 – x) = 3×2 – x3 […]
In this article, we shall study to prepare the forward difference table from the given data. Example – 1: If f(x) = x2 + x + 1, construct a forward difference table by taking x = 0, 1, 2, 3, 4, 5 i.e. 0(1)5. Hence find Df(o), D2f(1) and D3f(2). Solution: Given f(x) = x2 […]
In the last article, we have studied methods of preparation of alkenes. In this article, we shall study the reactions of alkenes Stability of Alkenes: The stability of alkenes is measured in terms of its heat of hydrogenation. The heat of hydrogenation of an alkene is defined as the amount of heat evolved when one […]
In the last article, we have studied what are alkenes and isomerism in them. In this article, we shall study different methods of preparation of alkenes. Preparation of Alkenes By Dehydration of Alcohols: Alcohols on heating in the presence of dehydrating agents Iike concentrated sulphuric acid or phosphorous pentoxide or anhydrous alumina etc. undergoes a loss […]
