The carbon resistor is the most common form of resistor used in electronics. They are made of a sturdy cylindrical resistive element with embedded wire leads or metal end caps. …
Gattermann Koch Reaction
Gattermann Koch Reaction involves formylation (addition of Aldehyde group) of an aromatic compound with the help of formyl chloride (produced by Carbon Monoxide and HCl) and Lewis Catalysts. The reaction …
Screw Gauge
A screw gauge is a tool used to measure very thin objects like sheets of metal or wires. It provides greater precision than Vernier’s Callipers. Sometimes it is also called a …
Difference Between SN1 and SN2 Reactions
SN1 and SN2 reactions are two kinds of organic reactions. Specifically, they are “Nucleophilic Substitution Reactions”. We are going to discuss the terminology involved here and find out the difference …
Dimensions of Surface Tension
Surface Tension is a measure of a liquid’s tendency to minimize its surface area. Dimensions of surface tension can be derived from its definition. It can be defined as the …
Cannizzaro Reaction
Cannizzaro Reaction is a chemical reaction that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to give primary alcohol and carboxylic acid. History This reaction was first …
Group 1 Elements
Group-1 Elements of the Modern Periodic Table consist of Hydrogen(H), Lithium(Li), Sodium(Na), Potassium(K), Rubidium(Rb), Caesium(Cs), and Francium(Fr). Out of these elements except for hydrogen, the remaining elements are popularly known …
Newton’s Law of Gravitation
Newton’s universal law of gravitation establishes a relationship between every particle and every other particle in the universe. The publication of the theory is called the “First Great Unification”, as …
Clemmensen Reduction
The Clemmensen reduction is a chemical reaction that allows the reduction of ketones to alkanes using zinc amalgam and concentrated hydrochloric acid. This reaction is named after Danish chemist, Erik …
Newlands Law of Octaves
Newlands’ Law of Octaves is an early attempt to classify elements based on periodic properties. It set the stage for later, more complete methods like Mendeleev’s and the Modern Periodic …
