I had asked a question earlier about how the “$\ce{-COOCl}$” functional group would be named.
I had received a satisfactory answer that helped me completely understand how that compound was named.
However, I have a much broader question in mind now.
Consider the "$\ce{-COOH}$" functional group. We know that it's called a carboxylic acid group, however I used to think, why wasn't ethanoic acid simply called as a 1-hydroxyethanal? I now know that "1-hydroxyethanal" has properties vastly different from both aldehydes and alcohols, and as a result, was named differently to acknowledge this difference. Many acid derivatives have been named (and behave) differently, as a result of the $\ce{C=O}$ group nearby.
However, these may not be the only molecules that are affected by the nearby $\ce{C=O}$ group. My earlier question had dealt with the $\ce{-COOCl}$ functional group (not to be confused with acyl chloride $\ce{-COCl}$). However, there are a lot more:
Of course, I did try to name these compounds myself.
- Cyanide is sometimes treated as a pseudohalide, so my guess is ethanoyl cyanide.
- It may be an anhydride of hydrogen sulfide and ethanoic acid, but I'm not very sure.
- Loong gave me an interesting way to name certain "anhydride" compounds in my previous question. This looks like an anhydride of hydroxylamine and ethanoic acid. So according what Loong told me, my guess is ethanoic hydroxylamine anhydride.
- This one look's rather crazy to me. Had this been posessing a $\ce{C-O-S}$ instead of a $\ce{C-S}$, this would have been an anhydride of sulfuric acid and ethanoic acid. But it's not, so I have no clue on how to name it.
- This one looks very familiar to an amide, infact a phosphorus analog of amide. For some reason, I feel like calling it ethanephosphide, although I don't know why.
- Like cyanide, even azide is considered a pseudohalide, so my guess is ethanoyl azide.
Please keep in mind, I am not asking for the explanations to the naming of all the six compounds I showed above, although it would be great if I could get the names alone. Rather, what I mean to ask is is there any simplified nomenclature that can deal with all these types of compounds in a simple way? Although I only showed six, I can go on as long as my imagination permits.
