The Lewis structure of HNO3 - Chemistry Stack Exchange
2015年5月22日 · $\begingroup$ It is very important to know that Lewis octet rule is one thing and the Lewis Formula another. That does not mean that they may not be combined. The main flaw of Lewis formula is that it can only describe covalent bonds with two electrons each. Hence a Lewis structure is never a complete representation of the bonding picture ...
Why this Lewis structure for HNO3 nitric acid is wrong?
2023年11月6日 · $\begingroup$ Lewis structures are a highly simplistic way of understanding bonding and bear almost no relation to the actual structures of real molecules. So the fact that this structure obeys the rules of lewis structures tell you nothing at all about whether this is the right structure of the compound. it isn't. $\endgroup$ –
Why does HNO2 not have resonance? - Chemistry Stack Exchange
2017年12月18日 · These are valid resonance structures of nitrous acid. You have to keep in mind though, that resonance does not change the geometry of a molecule (or molecular structure). The contribution of the Lewis structure with fewer formal charges to the total wave function will be much higher than the contribution of the other structure in this case.
What is the correct Lewis structure of NH3O?
2016年1月17日 · Technically, both the structures $\ce{H2N-OH}$ and $\ce{H3N\bond{->}O}$ may exist. However, in reality hydrogen atom is rather prone to migration and the second structure is not favorable. So, for a compound with composition $\ce{NH3O}$, the correct structure would be $\ce{H2N-OH}$.
Why is the structure of HNO3 have a central atom rather than …
2019年6月13日 · Why is the structure of $\ce{HNO3}$ have a central atom rather than being linear?. I know formal charges need to be reduced as much as possible, and if there was a structure with two oxygens and a hydrogen dangling off the nitrogen on one side and with a double bonded oxygen on the other, wouldn't that make all atoms in it have a formal charge of …
inorganic chemistry - How to explain the structure of HNO3 with a ...
2016年4月2日 · By using formula $\pi =6\mathrm{n}+2-\mathrm{V}$ where $\pi$ is number of $\pi$ electrons, $\mathrm{n}$ is number of atoms excluding all hydrogen atom, and $\mathrm{V}$ is total valence, the $\pi$ is $2$. It means that there would be one double bond in the structure of $\ce{HNO3}$ and the remaining bonds other than $\pi$ bond are $\sigma$ bond.
vsepr theory - How do I figure out the hybridization of a particular ...
2013年3月17日 · Start by drawing the Lewis structure. The least electronegative atom that is not a hydrogen goes in the center (unless you have been given structural arrangement). Determine the number of electron domains on the central atom. Determine the electron geometry using VSEPR. Correlate the geometry with the hybridization.
Why is H2N2O2, and not HNO, called hyponitrous acid?
2022年8月21日 · Historically, the acid was not analyzed but its silver salts and the early discoverers assigned a formula of the salts as AgNO, implying HNO for hyponitrous acid (Ueber die untersalpetrige Säure, DOI: 10.1002/cber.18770100257). In short, experimental measurements of the molecular weight decide that it is $\ce{H2N2O2}$ rather than $\ce{HNO}$.
Lewis Structure of OF+ - Chemistry Stack Exchange
2019年11月23日 · Experiments show that dioxygen is paramagnetic, i.e. it has unpaired electrons. If you try to write this as Lewis structure, you end up with 7 electrons on each oxygen (counting electrons in bonds twice), i.e. no octets either. For $\ce{OF+}$, you should be able to write the same Lewis structure (and the same MO diagram). Because fluorine has a ...
Rules to draw Lewis dot structures - Chemistry Stack Exchange
2024年12月18日 · In case 2 Lewis structures are possible the one with neutral atoms is more stable than the one with charged atoms. Also one in which central atom has the highest covalency is more stable. These structures will produce a resonance hybrid having characteristics more of the one which is more stable.
