quantum chemistry - Why is the molecular structure of water bent ...
Apr 14, 2020 · 3. Water has the formula $\ce {H2O}$ and we can draw a Lewis structure with two lone pairs on the central oxygen. As a physics student and not a chemist, I think to myself, "Okay, there are two lone pairs, they will repel each other" and so we arrive at the conclusion of bent shape. The issue in my mind is that I don't see why the lone electron ...
Does H2O have a resonance structure? - Answers
Jun 14, 2024 · Resonance occurs when multiple Lewis structures can be drawn to represent the same molecule or ion, indicating that the actual structure is an average of the different resonance forms. Does H2O ...
Why does HNO2 not have resonance? - Chemistry Stack Exchange
Dec 18, 2017 · Explain. Since the nitrogen dioxide ion has resonance, the N−O N − O bonds are equal as resonance is in reality a hybrid of all of the possible structures for a certain molecule. However, the answer then assumes that HNOX2 H N O X 2 has no resonance but rather one single and one double bond (N−O N − O and N=O N = O), and therefore not ...
Strength of HClO4 and resonance - Chemistry Stack Exchange
Mar 19, 2016 · For this reason, HF is a stronger acid than NHX3. In addition, the size of A is important. If A is very big, essentially it is harder to hold on to the hydrogen. Thus the H−A bond is weaker. This is why HI is a better acid than HF. Stability of the conjugate base. Charge delocalisation is key here.
Which compound has resonance structures? - Chemistry Stack …
Aug 13, 2019 · Which compound has resonance structures? A. CX6HX12 C X 6 H X 12. B. CHX3CHO C H X 3 C H O. C. NaBr N a B r. D. NaX2COX3 N a X 2 C O X 3. The answer key says D is correct, but I do not understand why NaX2COX3, N a X 2 C O X 3, which is an ionic compound between the polyatomic ion carbonate and sodium, can have resonance structures.
All resonance structures of the hydrogen molecule
Sep 4, 2016 · This answer written by Jan says that "a professor of mine claimed to have drawn some 18 (or was it 80?) different resonance Lewis structures." Please reproduce those resonance structures of the hydrogen molecule. If nobody is able to come up with that many, the answer with the most resonance structures would be accepted.
What are the correct resonance structures of nitrous oxide?
May 1, 2015 · The third structure is the ideal structure, i.e. the one with the highest agreement. I would expect it to have the highest contribution to the overall bonding. Structure 3 accounts for delocalisation effects and is one of the major contributions to the overall resonance stabilisation of the molecule. Basically you can see the character of this ...

inorganic chemistry - Why is carbon dioxide considered a Lewis …
In these depictions we can observe a resonance structure wherein carbon dioxide’s carbon has a positive charge and thus an electron sextet. If you look at the actual orbitals in question, the two populated bonding orbitals (one may be called nonbonding) have a high oxygen contribution while the antibonding π 3 orbital is a primarily carbon ...
What is the correct Lewis structure of NH3O?
Jan 17, 2016 · 6. Choose the most appropriate Lewis structure for NHX3O N H X 3 O among the two: and. The oxygen in the second case has 3 nonbonding pairs around it. I chose the first as an answer, yet the second seems to be the correct one. Can anyone please explain why? The second structure does exist in the crystalline phase.
