  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 …

  2. 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 …

  3. organic chemistry - How to determine what compounds are planar ...

    Feb 3, 2025 · Cyclopropane b always is planar, because you need (at least) three points to define a plane. Cyclobutane c is folded slightly, since there is a little room to noticeable wiggle one of …

  4. Cyclopentadiene planar - Chemistry Stack Exchange

    Sep 22, 2023 · 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

  5. 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 …

  6. Are there square planar complexes with sp2d hybridization?

    Aug 26, 2016 · Now my question is: 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 …

  7. 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?

  8. organic chemistry - Can we always use the planar representation …

    Nov 8, 2022 · In this case, both the planar representation and the conformational analysis lead to the same conclusion about the chirality of cis -1,2-dimethylcyclohexane (though for different …

  9. inorganic chemistry - Why is dinitrogen tetroxide a planar …

    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?

  10. Why isn't cyclobutane planar? - Chemistry Stack Exchange

    Aug 22, 2017 · In a planar model of cyclobutane all hydrogen atoms are in eclipsed positions, this is a cause of additional strain and is energetically less favourable. A relieve is obtained by …
