  1. 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 …

  2. Difference between radial, planar, angular and spherical nodes

    Jun 20, 2015 · 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 …

  3. 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?

  4. inorganic chemistry - Why is (NH4)2 [CuCl4] square planar complex but ...

    Sep 1, 2016 · Why is $\ce { (NH4)2 [CuCl4]}$ square planar complex but $\ce {Cs2 [CuCl4]}$ is tetrahedral even though both have same oxidation number of copper and same ligands?

  5. Why is the crystal field splitting energy larger for square planar than ...

    May 16, 2020 · 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 …

  6. Why is biphenyl not planar? - Chemistry Stack Exchange

    Jun 9, 2020 · I've seen in a lot of books that biphenyl is not planar. I don't know why that is, because both the carbon are $\\mathrm{sp^2}$ hybridized so it should be planar. Can someone explain it to me?

  7. Why is Ni[(PPh₃)₂Cl₂] tetrahedral? - Chemistry Stack Exchange

    May 19, 2019 · Since PPh₃ is strong field ligand and, the famous Wilkinson's catalyst, which also possess this ligand is square planar, then what makes the above complex tetrahedral?

  8. inorganic chemistry - Why is dinitrogen tetroxide a planar molecule ...

    May 15, 2020 · I was wondering why $\\ce{N2O4}$ is a planar species in spite of having a σ-bond in between the two $\\ce{N}$ atoms for free rotation. Does it not form a conformer?

  9. organic chemistry - Why is cyclooctatetraene non planar but the ...

    Jun 25, 2015 · It was mentioned that the neutral cyclooctatetraene molecule $\ce {C8H8}$ is non aromatic and has a tub-shaped conformation, but the dianion $\ce {C8H8^2-}$ is planar but aromatic.

  10. Are there square planar complexes with sp2d hybridization?

    Aug 26, 2016 · Are there Square Planar complexes in which the outer, vacant d-orbitals take part in hybridization (i.e- are there square planar complexes with sp2d hybridization) ?
