2023年9月20日 · Water (H 2 O) is a heteronuclear polyatomic molecule, containing three atoms from two different elements. The MO electronic configuration of H 2 O is (1a 1 2)(2a 1 2)(1b 2 2)(2a 1 ‘ 2)(1b 1 2). The absence of any unpaired electron in the Molecular orbital diagram of H 2 O reveals its diamagnetic nature. The bond order of H 2 O is 2.

H2O为V构型，分子点群为 C2v。 配体原子是不可能单独和中心原子成键的，必定是配体原子的轨道线性组合以后再和中心原子的轨道进行线性组合。 （道理很简单，如果是配体原子和中心原子单独成键，水分子的组成岂不是HO而不是H2O） 两个氢原子的轨道，分别在A1和B2有分量。 A1不可约表示--中心原子2s和2pz两个轨道，配体原子一个轨道；线性组合形成了三个分子轨道，由于有能量较低的2s存在，所以可直接得出为两个 成键轨道，一个 反键轨道。 B1不可约表示--中心 …

2009年12月29日 · An advanced molecular orbital diagram of H2O (water) for the inorganic or physical chemistry student.

We will walk through the steps below to construct the molecular orbital diagram of water. Step 1. Find the point group of the molecule and assign Cartesian coordinates so that z is the principal axis. The H 2 O molecule is bent and its point group is C2v. The z axis is collinear with the principal axis, the C2 axis.

Learn about the molecular orbital (MO) diagram for H2O, which illustrates the bonding and anti-bonding orbitals involved in the formation of water molecules. Understand the electron configuration and energy levels of these orbitals, providing insight into …

2023年6月14日 · First we'll look at an MO diagram for water, because it's pretty simple and water is very important. Then we'll look at the π MOs for the nitrate ion, so we can see the difference between MO theory and valence bond theory.

The molecular orbital (MO) diagram of H2O, also known as water, is a representation of the electronic structure of the molecule. It shows how the atomic orbitals of the hydrogen and oxygen atoms combine to form molecular orbitals.

In the molecular orbital diagram of H2O, the valence electrons of oxygen atomic orbitals and the hydrogen atomic orbitals form molecular orbitals through overlap. The oxygen atom contributes six valence electrons, while each hydrogen atom contributes one valence electron.

Use AO energies to draw MO diagram to scale (more or less). To this point we’ve built the group orbitals by inspection. For more complicated molecules, it is better to use the procedure given earlier: Find the characters of the reducible representation for the combination of valence orbitals on the outer atoms.
