  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. 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...

  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. Difference between radial, planar, angular and spherical nodes

    Mar 26, 2015 · Does this mean that all p orbitals have planar nodes and in d, only d 2 d z 2 has conical node while others have planar node. I am clear about radial/spherical nodes. Thanks.

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

    May 16, 2020 · 1 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. Aromaticity of [14]annulene - Chemistry Stack Exchange

    Feb 17, 2023 · The reason he gave is due to repulsions between hydrogens, the structure is no longer planar But later he told us that [14]annulene is aromatic. But isn't there a repulsion between …

  8. 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) ?

  9. Are carbocations necessarily sp2 hybridized and trigonal planar?

    Jul 12, 2017 · My copy of Pearson's Organic Chemistry (7e), Morrison and Boyd, under the section " Reaction intermediates ", accords a succinct description on the structure of carbocations: The central …

  10. 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?
