13.2: Molecular orbitals for ethene - Chemistry LibreTexts
Molecular orbitals for ethene (ethylene) In the bonding pi orbital, the two shaded lobes of the p orbitals interact constructively with each other, as do the two unshaded lobes (remember, the arbitrary shading choice represents mathematical (+) and (-) signs for the mathematical wavefunction describing the orbital).
An electron can be excited from the HOMO to the LUMO using light of a precise wavelength dependent on the energy difference between the two orbitals (since the orbitals are quantized). The electron can go back to it’s original orbital and heat (or light) is produced in the process.
Bonding orbitals in Ethylene (Ethene) sp2 - ChemTube3D
Bonding orbitals in Ethylene (Ethene) sp 2 CONTROLS Use the buttons to display the sp 2 orbitals that make up the sigma framework and the remaining p orbitals which form the pi-bond.
1.8: sp² Hybrid Orbitals and the Structure of Ethylene
An ethylene molecule is said to be made up of five sigma bonds and one pi bond. The three sp 2 hybrid orbitals on each carbon orient to create the basic trigonal planer geometry. The H-C-C bond angle in ethylene is 121.3 o which is very close to the 120 o predicted by VSEPR. The four C-H sigma bonds in ethylene .

Molecular Orbitals: Ethene (Ethylene) - Oregon State University
2014年4月14日 · Ethylene is the simplest molecule that has a double bond. As we saw from the valence bond model, we should find the presence of a σ-bond framework, and a π-bond between carbons. (Calculated at the B3LYP/cc-pvdz level using Jaguar, version 7.8, Schrödinger, LLC, New York, NY, 2011.) Let's start with the π bond: click on MO 6 in the list below.
1.8 sp 2 Hybrid Orbitals and the Structure of Ethylene - OpenStax
To complete the structure of ethylene, four hydrogen atoms form σ bonds with the remaining four sp 2 orbitals. Ethylene thus has a planar structure, with H–C–H and H–C–C bond angles of approximately 120°.
30.1 Molecular Orbitals of Conjugated Pi Systems - OpenStax
According to molecular orbital (MO) theory, the p orbitals on the sp2 -hybridized carbons of a conjugated polyene interact to form a set of π molecular orbitals whose energies depend on the number of nodes they have between nuclei.
