3 天之前 · VSEPR. VSEPR stands for Valence Shell Electron Pair Repulsion model or theory. Like charges repel each other. So, the valence electrons being negatively charged have a tendency to repel each other within a molecule. VSEPR theory explains the shape by minimizing the electronic repulsion.
C2H4 lewis structure, molecular geometry, bond angle
2023年10月11日 · The molecular geometry of C2H4 is trigonal planar and its electron geometry is also trigonal planar according to VSEPR (Valence shell electron pair repulsion theory). As e ach carbon in the C2H4 molecule has Sp² hybridization and with two hydrogens it makes the structure look like a triangular planar which is two-dimensional.
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 .

2021年7月16日 · Ethylene comprises two Carbon atoms with four Hydrogen atoms surrounding it. Carbon is in group 4 of the periodic table with the electronic configuration [He] 2s22p2. Therefore, the two Carbon atoms contribute 4 x 2 = 8 valence electrons. Hydrogen has an electronic configuration of 1s1.
Hybridization: Structure of Ethylene | MCC Organic Chemistry
Valence Shell Electron Pair Repulsion (VSEPR) Theory is used to predict the bond angles and spatial positions of the carbon and hydrogen atoms of ethene and to determine the bond order of the carbon atoms (the number of bonds formed between them).

2018年2月7日 · VSEPR theory: Electron pairs (free and bonded) are distributed in the space around the central atom of the molecule, where the repulsion between them is the minimum to form the most stable shape of the molecules.
3.10: Molecular Shapes- The VSEPR Theory - Chemistry LibreTexts
Small molecules—molecules with a single central atom—have shapes that can be easily predicted. The basic idea in molecular shapes is called valence shell electron pair repulsion (VSEPR). It basically says that electron pairs, being composed of negatively charged particles, repel each other to get as far away from each other as possible.
