  • How can I tell whether or not a molecule is planar?
    Otherwise, its structure allows it to be planar Even though the molecule will have a structure that allows for it to exist in a planar conformation, there may be some many that do not persist in a planar conformation due to steric effects, or complex three dimensional geometries
  • How to determine what compounds are planar?
    If I'm not wrong, sp and sp2 hybridized carbon atoms are always planar, however none of the compounds given in the question seem to have a planar configuration as every carbon atom is sp3 hybridize
  • Difference between radial, planar, angular and spherical nodes
    What is the difference between them? I think radial nodes and spherical nodes are the same, and angular and planar nodes are the same Reference Finally, how many spherical nodes are there
  • Why is the crystal field splitting energy larger for square planar than . . .
    It is because of the fact that square planar complexes are formed by much strong ligands with d8-metal cation of 3d- series transition metals cation and 4d or 5d-series transition metal cation with either weak or strong ligands The very strong ligands and 4d or 5d-series transition metal cations are responsible for higher crystal field splitting
  • Why is [PdCl4]2- square planar whereas [NiCl4]2- is tetrahedral?
    The molecule $\ce { [PdCl4]^2-}$ is diamagnetic, which indicates a square planar geometry as all eight d electrons are paired in the lower-energy orbitals However, $\ce { [NiCl4]^2-}$ is also $\mathr
  • Cyclopentadiene planar - Chemistry Stack Exchange
    Cyclopentadiene has a sp3 carbon yet it is said to be planar I am not able to understand and haven't been able to find a credible source Some sources say it to be non-planar
  • inorganic chemistry - How to use crystal field theory to predict . . .
    How can one predict whether a given complex ion will be square planar or tetrahedral when its coordination number is 4 using crystal field theory? Is it possible to theoretically predict this?
  • How to identify whether a molecule is planar [closed]
    The concept of a plane of symmetry is easier to understand with molecules which are planar by itself Benzene, for example, has such a plane which may accommodate simultaneously all carbon and hydrogen atoms: However, planarity of molecules is not a requirement to identify such planes Even if a construction of the cyclobutane molecule with model kit illustrates you the non-planarity of the
  • organic chemistry - Applying Huckels rule to non-planar compounds . . .
    Applying Huckel's rule to non-planar compounds Ask Question Asked 7 years, 6 months ago Modified 4 years, 2 months ago
  • Why is tetraamminecopper (II) a square planar and not a tetrahedral . . .
    All Cupric complexes irrespective of the kind of ligands is always dsp2 square planar hybridization Now the question is that why this is so? In tetrahedral complexes when Cu is in +2 state the one electron from 4s2 and one from 3d orbital gets removed and so it a 3d9 complex Now from 3d9 complex one electron goes to 4p orbital and in this way it now becomes 3d8 and dsp2 complex
