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 $\ce {sp^3}$ hybridized carbon (or nitrogen) atom or two $\ce {sp^2}$ hybridized atoms of carbon/nitrogen …
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 …
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 …
organic chemistry - Why is cyclooctatetraene non planar but the ...
Jun 25, 2015 · 4 If cyclooctatetraene were planar, it would be an antiaromatic compound according to Hückel's rule, because it has 8 π-electrons. However, since its lowest energy …
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 …
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 …
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 …
Are carbocations necessarily sp2 hybridized and trigonal planar?
Jul 12, 2017 · The planar coordination is a result of a favourable electronic state. Obviously there will be other interactions at play, but in a first approximation the above is always true.
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?
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?
