  1. How can I tell whether or not a molecule is planar?

    So a general simple rule is that: the molecule will not be planar if there is an \cesp3 \ce s p 3 hybridized carbon (or nitrogen) atom or two \cesp2 \ce s p 2 hybridized atoms of …

  2. 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?

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

    Feb 3, 2025 · 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 …

  4. How to identify whether a molecule is planar [closed]

    Aug 27, 2020 · 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 …

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

    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 …

  6. 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 …

  7. How is aniline considered a conjugated system?

    Apr 1, 2025 · For conjugation there must be unhybridized, parallel and adjacent 2p orbitals. But in case of aniline, the hybridization of nitrogen is sp3, which makes it an non-planar system. Yet …

  8. 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?

  9. 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 …

  10. 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 …
