Physical organic chemistry is that branch of organic chemistry which deals with mechanistic studies of chemical reactions for the elucidation of structure and reactivity of organic compounds and reaction pathways. For this purpose scientists in this area of research use spectroscopic methods and techniques such...

Electrophilic aromatic substitution refers to a reaction of the benzene ring in which an electrophile such as a nitro group is added to the ring with subsequent elimination of a hydrogen atom. This type of reaction is typical for aromatic compounds and in particular for...
How to make ice cream in a bag
By: Harjot Jassal
Cold, creamy and luscious, ice cream is a much-revered treat. While this dessert is readily available in the freezer cases of grocers and specialty stores, homemade ice cream is in a world of its own. When you make your own ice cream, you combine fresh...
The chemistry of organic explosives
By: Tarek Musslimani
Organic explosives are those types of explosives which are composed of hydrocarbons in addition to an oxidizing source which will help to complete the combustion of the hydrocarbon C-H bonds. In particular and hydrocarbons in general are used often to generate heat due to their...

Generally speaking, in organic chemistry there are three types of reactions that govern most reactions. These are: addition reactions and substitution reactions in addition to elimination reactions. These reactions will be discussed sequentially one after the other. The first type of reactions in organic chemistry...
The basics for making crystals
By: Joan Collins
According to Google, crystals are "a solid formed by the solidification of a chemical and having a highly regular atomic structure." They do appear naturally in nature, but they can also be man-made. From rock candy to magnificent displays, crystals can be formed at...
Element facts: Carbon
By: Henry Chew
Carbon is a naturally occurring element and can be found abundantly throughout the universe. As a matter of fact, it is the fourth most abundant element in our world after hydrogen, helium and oxygen. Most of us may not be aware of this but in...
What is an atom?
By: Lawrence George
The Greek philosopher Democritus, who lived between 460 and 370 BC, thought that matter was composed of tiny, indivisible objects in perpetual motion. He called these theoretical objects "atoms" - from the Greek word "atomos", meaning something that could not be cut. In Democritus' time...
