How does more s character shorten bonds and strengthen bonds?
I'm aware that having more s character means that electrons are in the lowest energy state (?) and very close to the positive atomic nucleus. But then what’s the connection between having electrons ...

Why is the statement regarding the strength of ionic bonds reasonable? [closed]
In largely ionic compounds (e.g. NaBr and NaI), it seems to be generally true that, the greater the differences of electronegativity between the forming substances (i.e. The compound has more "...

What is the molecular orbital diagram of hydroxide anion? [closed]
Context
I am a teacher, and, during a class, my student asked me to draw the molecular orbital (MO) diagram of the hydroxide anion ($\ce{HO-}$). First, I made the diagram on the left, and then, when ...

Would a hypothetical Og2 +235 form a chemical bond?
In a hypothetical (?) Og2+235 we would have a simple sigma bonding orbital occupied by one electron (leading to a bond order of 1/2). But how to take into account the giant repulsion of the two nuclei?...

How do I determine the hybridization of terminal atoms? [duplicate]
I've read that terminal atoms do not undergo hybridization because there is no need to.
For example, CF4, C undergo sp hybridization, but fluorine do not hybridize.
How about CO2? Why is oxygen sp2 ...

Is the shortness of boron trifluoride's bonds better understood and explained now than it was "way back" in the 20th century?
Wikipedia's Boron trifluoride; Structure and bonding says:
In the boron trihalides, BX3, the length of the B–X bonds (1.30 Å) is shorter than would be expected for single bonds,7 and this shortness ...

Can two hydrogen atoms with parallel electron spins form a covalent bond?
Is it possible for two hydrogen atoms with parallel electron spins (i.e. a pair of spin-up electrons, or a pair of spin-down electrons)
to form a covalent bond? I've seen some say there is no sigma ...

In the LCAO method for $H_2^+$, why do we only add or subtract orbitals but never alter one of the phases of the orbitals?
TLDR:
Atkins' physical chemistry contains the quote "In general, from N atomic orbitals we can build N molecular orbitals". In the case of $H^+_2$, we use a combination of N=2 orbitals to ...

Role of 'p' Orbitals in Graphite Carbons
In the graphite arrangement of carbons, if we model them according to hybridization theory, the carbons in graphite are sp2 hybridized. This would mean that one s and two p orbitals hybridize, making ...

How is kinetic energy accounted for when describing diatomic bonds with a Morse potential?
The Morse potential can be used to describe the potential energy of the a diatomic bond:
This curve suggests that the lowest state $v = 0$ is the most stable, since it has the lowest potential energy....

Confusion regarding $\delta$ charge compared with electronegativity
I heard on a lecture of an online site that, let us say, we have two orbitals (1 and 2). Now, it will be like a spherical cloud. Now, what they say is that
Now, we can notice that for orbital number ...

Regarding the probability density of finding an electron in between a bond
I'd found the image attached on a website explaining the molecular orbital theory.
My question is, shouldn't the graph have a maximum at the middle of the two hydrogen atoms? since my intuition tells ...

Comparison between Molecular Orbital Theory and Valence Bond Theory
I have been reading about introductory Molecular Orbital Theory lately. Till now, I have used Valence Bond Theory to evaluate bonding. I have a few questions about it:-
In VBT, we used the idea that ...

Can single molecules of C and O2 react in isolation, and if so how will momentum be conserved?
I am trying to figure out how is it possible to reconcile the reality of exothermic reactions, which means that kinetic energy is transferred to (heats) the surrounding matter, with the principle of ...
