Our teacher gave us a rule that more electronegative atom is present at a greater distance i.e. the bond which is longer in these molecules and thus explained the structure of XeF3Cl4 by saying the axial bond length is shorter due to less repulsion (angle is 90 compared to 72 in equatorial) and so Cl being less electronegative will occupy axial ...

Sep 24, 2022 · The bond length depends on "what the electrons are doing". For example, $\ce{H2}$ and $\ce{H2+}$ have different bond lengths (the latter is a molecular ion, so maybe outside of the scope of the question).

Oct 9, 2015 · With a carbon-carbon double bond, 4 electrons are shared between the two carbon atoms and 6 electrons are shared in a triple bond. Having additional electrons between the two atoms 1) improves the bonding overlap (makes the bond stronger) between the two carbon atoms and 2) better screens the two carbon nuclei form each other.

Mar 27, 2014 · Measured $\ce{CO}$ bond length is 1.128 Å, $\ce{CO^{+}}$ is 1.115 Å. Given the following carbon monoxide MO diagram, from where is the electron removed to afford the cation with a shorter bond length? $\ce{CO}$ has a dipole …

Dec 13, 2013 · Because atomic radii of elements tend to decrease across a period , and bond length increases with atomic radius, the bond lengths are expected to decrease in the following order: C (C-C bond) > B, D (C-N) > A (C-F).

Dec 19, 2024 · Yes, that it quite true. EWG reduce the electron density on the double bond of the alkene, making it more susceptible to backbonding and thereby reducing the bond order of the double bond. "but at the same time due to high EN it would not donate it's orbital thereby not forming strong sigma bond. And hence weaker synergic bond"

Dec 24, 2016 · What is the order of bond length of $\ce{O-O}$ in the following compounds: $\ce{H2O2, O2F2, O2Cl2}$ In my view since fluorine is more electronegative than oxygen it will attract the bonded electrons towards itself resulting in low bond length in case of $\ce{O2F2}$ than in case of $\ce{O2Cl2}$.

Apr 20, 2015 · We can find the bond lengths in the literature. The carbon-carbon double bond length is 1.338 Å, typical for a double bond . The carbon-carbon single bond length is 1.454 Å, shorter than expected due to resonance. All of the carbons are $\ce{sp^2}$ hybridized, which means that all of the bond angles should be ~120°.

May 19, 2021 · In another unusual case, I see that $\ce{N-N}$ bond length in $\ce{N2O3}$ (the blue asymmetric form) is $\pu{1.86 Å}$!! That is very weak for a nitrogen single bond. Is there a satisfactory explanation for this? And amazingly molecules with such long bonds tend to have a nonplanar structure due to bond rotation but $\ce{N2O4}$ is planar.

Dec 3, 2019 · Estimate the bond length of 12C16O (pure rotational spectrum) given J''=3 (15.356 cm-1) and J'=9 (38.356) I understand that the first step is the calculate the rotational constant. So to do this I assume I would use one frequency value and one J value? And the equation to use would be $$\nu = BJ(J+1)$$
