Welcome to this video on radicals.<\/p>\n<p>Within chemistry, the term <em>radical<\/em> (more commonly called a free radical), refers to an atom, <a class=\"ylist\" href=\"https:\/\/www.mometrix.com\/academy\/molecules\/\">molecule<\/a>, or ion that has one or more unpaired valence electrons that are covalently bonded.<\/p>\n<p>Though there are some outliers, because of the unpaired electrons, free radicals become extremely reactive with other substances and with themselves.<\/p>\n<p>Free radicals can often cause a chain reaction. This is because when one free radical searches to bond with another unpaired valence electron which regenerates a new radical causing a domino effect of reactions. Propagation phase is the term used to describe this series of reactions.<\/p>\n<p>Radicals can detach hydrogen or other atoms from several different solvents and reagents; this is seen in a group transfer reaction (&#8220;transfer reaction&#8221; meaning the transfer of an atom or group of atoms from one molecule to another).<\/p>\n<p>In general, most free radicals that occur organically have very short lifespans and disproportionate (this is a group transfer into dissimilar molecules) or dimerize (meaning that an atom or atoms are transferred to similar molecules), and these reactions happen at a very specific diffusion controlled rate. Diffusion controlled rate means that they react at the moment of contact.<\/p>\n<p>Free radicals are a very important, specific, and intricate part of chemistry that can oftentimes be hard to understand.<\/p>\n<p>I hope this video was helpful!
