Share: 50 21K Carboxylic acid is a class of organic compounds that are characterized by the presence of carboxyl group (-COOH) in them. The general formula for carboxylic acids is R – COOH where R refers to the rest of the molecule. Acidity of carboxylic acids is generally higher compared to simple phenols as they […]
Preparation of Sulphuric Acid by Cont...
Share: 50 21K We will first start by addressing the question what is sulphuric acid. Well, sulphuric acid is basically an oxidizing agent, a strong mineral acid, and a dehydrating agent. Sulphuric acid has the chemical formula H2SO4. The acid is a colorless liquid. It is soluble in water and generally releases heat on contact. […]
Uses of Methanol and Ethanol in Every...
Share: 50 21K Ethanol and methanol may look similar and belong to the same primary type of alcohol but actually they are quite different. If we put methanol and ethanol in two different glasses, they will look the same. Methanol is a colorless volatile liquid with special odor and it burns to give a white […]
Pseudo First Order Reaction – Chemica...
Share: 50 21K In this section, we will learn about the pseudo first order of reaction and their rate equations. To begin with, reactions that appear to be second order in nature but are approximated as a first-order of reaction on close analysis. For example, a second – order of reaction is given by the […]
Calcium Oxide
Share: 50 21K Calcium oxide, also known as quicklime, is an alkaline substance which has been in use since the medieval age. It is believed that quicklime is one of the oldest chemicals known to the human race. It can also be referred to as burnt lime. Preparation of calcium oxide Calcium oxide can be […]
Electrophilic Substitution Of Benzene
Share: 50 21K Resonance involved in the benzene ring makes the delocalized electron span effectively over the carbon atoms in the benzene ring. It partially stabilizes the arenium ion too. Partial stability of arenium ion makes benzene highly prone to electrophilic substitution reactions. Electrophilic substitution of benzene is the one where an electrophile substitutes the […]
Difference Between Endothermic and Ex...
Share: 50 21K This topic explains the difference between Endothermic and Exothermic Reactions. There are number of chemical reactions in chemistry and there are divided into many sub and main reactions. Similarly the endothermic and exothermic reactions in chemistry. These release energy in the form of sound, light, cold or heat. In simple terms, the […]
Acidity of Carboxylic Acids
Share: 50 21K Carboxylic acid is an organic compound containing carboxyl group (COOH) attached to an alkyl or aryl group. They react with metals and alkalis to generate carboxylate ions. These reactions of carboxylic acids indicate their acid nature. Acidity of carboxylic acids is higher in comparison to simple phenols as they react with weak […]
Ores And Minerals
Share: 50 21K Isolation of elements in Chemistry class 12th aims to teach the students about the various processes of extraction of metals from ores. Very few metals such as the noble metals, i.e.,Gold, Silver, Platinum, etc are present in their original metallic forms in nature. Metallurgy is the field of science which deals with […]
Rate Of Reaction
Share: 50 21K When we talk about chemical reactions, it is a given fact that rate at which they occur varies greatly especially in terms of speed. Some are nearly instantaneous, while others usually take some time to reach the final equilibrium. So today we will learn about and understand what exactly is rate of […]
