Free-radical halogenation
open-in-new
<p>In <a href="/facts/Organic_chemistry/djxhxaNg">organic chemistry</a>, free-radical halogenation is a type of <a href="/facts/Halogenation/vYrGVWcJ">halogenation</a>. This <a href="/facts/Chemical_reaction/GpqWlKrz">chemical reaction</a> is typical of <a href="/facts/Alkane/Qam7Hvmf">alkanes</a> and <a href="/facts/Alkyl/vmEk8X4v">alkyl</a>-substituted <a href="/facts/Aromatic/wK0DzRY6">aromatics</a> under application of <a href="/facts/UV_light/kncBUqn5">UV light</a>. The reaction is used for the industrial synthesis of <a href="/facts/Chloroform/gvzuJMXa">chloroform</a> (CHCl3), <a href="/facts/Dichloromethane/mHyeTD2D">dichloromethane</a> (CH2Cl2), and <a href="/facts/Hexachlorobutadiene/Hh0f2WfI">hexachlorobutadiene</a>. It proceeds by a <a href="/facts/Free-radical/qFymuVoT">free-radical</a> chain mechanism. </p>
