Can you describe me free radical with examples? |

Answer» Yours welcome ??? Ankit your answer is suitable for me to discribe free radical with examples. And thanks for the answer. Thanks Free radical, is the term used to describe a particle that has an unpaired electron. An electron is the negative portion of an atom and is found outside the nucleus, or the center of the atom. As you can see from the image on screen of the Lithium atom, electrons can be found close to the nucleus or far away from the nucleus. For this lesson, we\'re going to focus on the valence electrons, which are the electrons furthest away from the nucleus, and the electrons most likely to be involved in reactions. For example :Let\'s say you have two chlorine atoms that are bonded or stuck, together making a molecule.Given enough heat, these two chlorines will break apart and each will end up taking their valence electrons with them. You can see from the image that each has seven valence electrons. Now each one has an unpaired valence electron. Uh oh! You know what that means. Yep, they\'re free radicals. And they are very reactive and, since electrons don\'t like being unpaired, they will try to find another particle to react with. Free redicals:free radical, in chemistry means , a molecule or atom that contains an unpaired electron but is neither positively nor negatively charged. Free radicals are usually highly reactive and unstable. They are produced by homolytic cleavage of a covalent bond (see chemical bond); i.e., each of the atoms connected by the bond retains one of the two electrons making up the bond. The homolytic cleavage of a hydrogen molecule, H2, produces two hydrogen free radicals (hydrogen atoms). Similarly, two chlorine free radicals can be produced from a chlorine molecule. Homolytic cleavage of the carbon-bromine bond in methyl bromide, CH3Br, would produce a methyl free radical and a bromine free radical. The term free is often dropped in referring to free radicals; this could lead to confusion if the term radical were used synonymously with group in organic chemistry, e.g., by calling an alkyl group an alkyl radical when free radical was not intended. I searched it on Google but I don\'t understand so can anyone help me to complete my project? |
