How is a pi bond formed in ethene
Web18 mrt. 2024 · Initially, both ethylene molecules are weakly coordinated to Cr(I) via π-bonding interactions. The relatively weaker nature of the π-bonding is reflected in the relatively shorter C-C bonding distances of 1.348 and 1.359 Å, which are 0.017–0.028 Å longer than the calculated C=C distance in free ethylene.

Classical C-C bond forming reactions such as the Stille and Suzuki coupling reactions have been widely used in the past for this purpose. More recently, direct (hetero)arylation polymerization (DHAP) has earned a place in the spotlight with an …
WebThis is how Atkins depicts it : In simple terms, after forming a sigma-bond (a pre-requisite for pi-bonds), the two atoms get locked along the inter-nuclear axis. As a result, the orbitals available for pi-bonding can only partially overlap, thus forming a weaker bond. Share Improve this answer Follow edited Jun 19, 2014 at 7:00 Melanie Shebel
