Diamond

Diamond is one of the allotropes of pure carbon. It is a crystalline covalent solid found in alluvial gravels, kimberlite pipes and glacial tills. It occurs in all shapes and sizes and is found in South Africa, Brazil, Russia, Australia, USA and India. The Orapa mines in Botswana is the world’s largest, but Russia and […]

Dehydration of Alcohols

Alcohols are compounds with one or more -OH groups that bond with the carbon atoms and are widely used in pharmaceuticals and many industries. The dehydration of alcohol means the removal of water to form alkenes and other products. The best way to make alkenes is by dehydration of alcohol. It is a process through

Dalton’s Law of Partial Pressure

Introduction According to this law the total pressure exerted by a mixture of gases is equal to the sum of the partial pressures exerted by an individual gas. As for example the total pressure exerted by two gases A and B is equal to the sum of partial pressures exerted by gas A and gas

Crystallisation

Introduction Crystallisation is the interaction by which a strong structure, where the particles or atoms are exceptionally coordinated into a design known as a precious stone. A portion of the ways by which gems structure are hastening from an answer, freezing, or all the more seldom statement straightforwardly from a gas. Traits of the subsequent

Covalent Bond Fission – Homolytic and Heterolytic (Free Rradicals, Carbocations and Carbanions)

A covalent bond occurs when two different atoms share electrons in the traditional sense. As a result, a single bond, or a sigma bond, consists of two electrons. A chemical reaction occurs when old bonds break down and new ones are formed. In contrast, chemical bonds may be disrupted in several ways. Additionally, the way

Conjugate Acid Base Pairs

Lemon juice, vinegar, and ant bites all have one thing in common; they are acids. On the other hand, daily use objects like soaps, detergents, and toothpaste also have one thing in common; they are all bases. Acids and bases surround us everywhere we go. The reaction between acids and bases is crucial for a

Conformations: Sawhorse and Newman Projections (of ethane)

What stream to choose after 10th? Introduction The spatial arrangements of atoms in a molecule that can be obtained through rotation around one or more single bonds like Carbon-Carbon(C-C) bonds are known as conformation or conformational isomers. Rotational energy functions as a barrier in single bond rotation. The 12 KJ/mol barrier must be overcome to

Confirmation for Chromyl Chloride Test

Chromyl chloride is a chemical compound known by the chemical name CrO2Cl2. They are tetrahedral and appear as dark red blood. Mostly they are made of chromium as an initial derivative. It works as an oxidising agent and is found to exhibit oxidation properties to oxidise toluene into Benzaldehyde.  Confirmation for Chromyl Chloride Test One

Conduction Electrons

Similar to the concept of free electrons, it is also important to cover the topic of conduction electrons in similar detail. Although they show different behaviour in the case of semiconductors and metallic solids, they hold equal importance as free electrons due to the difference in statistical methods used to measure their concentrations in a

Concentration, Temperature, Pressure and Catalyst

A simple chemical reaction is a change in the concentration of reactants and the formation of products. When the system reaches the stage in which there is no further change in concentration of reactants or products with time, the state is known as a chemical equilibrium. In this state, neither the concentration of the reactants
