### Are resonating structures real or not? [duplicate]

We say that hybrid structure is real. It has distinct properties as compared to its Resonating Structure. Is it because that all the experiments we carry out are on a sample, lots of molecules are ...

### Resonance in ozone and benzene [duplicate]

In inorganic chemistry, I learnt that stability of some atoms like ozone cannot be explained by one structure alone and hence the hybrid of possible structures is taken and assumed to be the structure ...

### How does actually negative charge travel in phenol from ortho to para to ortho? [duplicate]

When we say negative charge flows from ortho to para position, and electron density at ortho and para is more, where does electron actually stay at ortho and para? Is it at $p_\mathrm{z}$ orbital or ...

### Does benzene structure stand for a single resonance form or the whole molecule?

It is known that benzene has two main resonance forms Often we still draw benzene molecule as one of them My question is, actually when we draw the lower figure, do we refer to the whole benzene ...

### How to determine the worst resonance structures out of a given set?

So I was "happily" doing organic chemistry homework when I came across this question: For 1-methoxy-1,3-butadiene, which of the following resonating structure is the least stable? \begin{...

### What are the important implications to the field of chemistry, if any, of the recently confirmed hexavalent carbon species?

I’m struggling to understanding the true nature and implications of recent confirmations of the existence of stable species containing carbon atoms bound six (in another case 5) other carbon atoms. Is ...

### What is the most “important” resonance structure of SCN⁻?

Numerous online references say that $\ce{SCN-}$ has two resonance structures: I am wondering why this structure is not also possible? I expect structure 3 to be rare because of the high formal ...

### What is the “resonance hybrid” of benzene?

In my book, to explain the structure of benzene, it referred to the idea of resonance: The idea of resonance is that the actual molecule is a definite structure that is a hybrid of two or more ...
