Free radicals class 11
WebA free radical is a species which has one or more unpaired electrons. In the species where all electrons are paired the total magnetic moment is zero. In radicals, however, since there are one or more unpaired electrons. There is a net magnetic moment and the radicals as a result are paramagnetic. Free radicals are usually defected by electron ...

In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has unpaired valence electrons or an open electron shell, and therefore may … WebChemical species having one or more unpaired electrons are called free radicals. Homolytic bond fission leads to the formation of free radicals. The free radicals are odd electron molecules and are highly reactive. Most organic radicals are quite unstable and very reactive. There are two kinds of radicals, neutral radicals, and charged radicals.
WebCarbocation. A carbocation is a molecule in which a carbon atom has a positive charge and three bonds. We can basically say that they are carbon cations. Formerly, it was known as carbonium ion. Carbocation today is defined as any even-electron cation that possesses a significant positive charge on the carbon atom. Web1. These are the compounds of carbon with H, 0, N, S, P, F, CI, Br and 1. 2. These are generally found in living organisms. e.g., carbohydrates, proteins etc. 3. These may be gases, liquids or solids. 4. Being covalent in nature, these have low boiling point and melting point and soluble in organic solvents. 5.
