The 18 Electron Rule is similar to the octet and duplet rules, as it is used to predict stability. There are two 18 electron rules to be precise; one is …
Hell-Volhard Zelinsky Reaction is an organic reaction by which the carboxylic acids are halogenated at the α-carbon atom. This reaction is named after the 3 German-chemists namely: Carl Magnus Von …
Plant Hormones (also referred to as phytohormones) are signal molecules created at intervals of plants in relatively low concentrations. Plant hormones manage all aspects of plant growth and development, from …
The Wurtz Fittig Reaction is basically an organic chemical reaction in which Aryl halide reacts with alkyl halides and sodium metal in the presence of dry ether which yields substituted Aromatic compounds. The reaction …
Duplet Rule is similar to octet rule in its sense that it describes stability of the atom of an element using the number of electrons present in its valence shell. …
The Aufbau Principle dictates how electrons are filled in the atomic orbitals of an atom in its ground state. What is the Aufbau Principle? The Aufbau principle states that, hypothetically, …
The Group 17 Elements include Fluorine, Chlorine, Bromine Iodine, Astatine and Tennessine. These elements are also called Halogens, as they produce salts, when they react with metals. History The Fluorine …
Set Theory and its Operations are probably the most fundamental branch of mathematics required for any thorough study of mathematics. Mathematicians like George Cantor, Richard Dedekind, Zermelo, and Frankel developed our …
The group 16 elements of the modern periodic table consists of 5 elements, namely Oxygen, Sulphur, Selenium, Tellurium, Polonium and Livermorium. The elements of this group are also called Chalcogens …
