WebThe pi bond is a weaker and more reactive bond than a sigma bond, making it susceptible to attack by halogens. When a halogen reacts with an alkene, the pi bond breaks to form a reactive intermediate, a halonium ion, which can then react with the halogen to form a dihalide. This reaction mechanism is known as halogenation. On the other hand ...

WebJan 23, 2024 · This extensive sideways overlap produces a system of pi bonds which are spread out over the whole carbon ring. Because the electrons are no longer held between just two carbon atoms, but are spread over the whole ring, the electrons are said to be delocalized. The six delocalized electrons go into three molecular orbitals - two in each. WebSigma and pi bonds are formed by the overlap of atomic orbitals. Sigma bonds are formed by end-to-end overlapping and Pi bonds are when the lobe of one atomic orbital …
