  2. Phosgene - Wikipedia

    en.wikipedia.org/wiki/Phosgene

    Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å , the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111.8°. [ 10 ] Phosgene is a carbon oxohalide and it can be considered one of the simplest acyl chlorides, being formally derived from carbonic acid .

    where μ is the electric dipole moment of the effectively polarized water molecule (2.35 D for the SPC/E model), μ 0 is the dipole moment of an isolated water molecule (1.85 D from experiment), and α i is an isotropic polarizability constant, with a value of 1.608 × 10 −40 F·m 2. Since the charges in the model are constant, this ...

    The steric number of a central atom in a molecule is the number of atoms bonded to that central atom, called its coordination number, plus the number of lone pairs of valence electrons on the central atom. [11] In the molecule SF 4, for example, the central sulfur atom has four ligands; the coordination number of sulfur is four. In addition to ...

  6. Water cluster - Wikipedia

    en.wikipedia.org/wiki/Water_cluster

    Detailed water models predict the occurrence of water clusters, as configurations of water molecules whose total energy is a local minimum. [6] [7] [8]Of particular interest are the cyclic clusters (H 2 O) n; these have been predicted to exist for n = 3 to 60.

    In contrast to localizing electrons within their atomic orbitals in valence bond theory, the molecular orbital approach considers electrons to be delocalized across the entire molecule. The simple MO diagram of H 2 O is shown on the right. [2] [3] Following simple symmetry treatments, the 1s orbitals of hydrogen atom are premixed as a 1 and b 1 ...
