Organic chemistry: Are all non-aromatic carbon chains aliphatic?

Click For Summary
The discussion centers on the classification of hydrocarbons in organic chemistry, specifically whether all non-aromatic hydrocarbons are aliphatic. It is clarified that hydrocarbons are categorized into two main classes: aromatic and aliphatic. The distinction is emphasized, with the assertion that non-aromatic hydrocarbons are indeed classified as aliphatic by definition. Participants suggest reviewing textbook classifications and provided links to Wikipedia articles for further clarification. The conversation highlights the importance of precise terminology, noting that "carbon chain" may be misleading in this context. Overall, the consensus is that a careful understanding of these classifications is essential for clarity in organic chemistry.

Are all non aromatic carbon chain aliphatic ?

"Carbon chain" seems a bit inprecise. If one rephrases the question to "Are all non aromatic hydrocarbons aliphatic ?" I recall the answer is yes by definition of basic classifications?

No, or as best I can understand, I believe no. One kind is distinct from the other kind. Review this classification from your textbook. For alternative review or maybe reenforcement, you might look at these two articles.

I understood this stuff better, but a very very long time ago.
Incorrect. Read the first sentence of the first link you posted:
“In organic chemistry, hydrocarbons(compounds composed solely of carbon and hydrogen) are divided into two classes: aromatic compounds and aliphatic compounds”

Correct.
 

Thread 'Molecular-level explanation of macroscopic phenomena: dissolving'

What I know and please correct me: a macroscopic probe of raw sugar you can buy from the store can be modeled to be an almost perfect cube of a size of 0.7 up to 1 mm. Let's assume it was really pure, nothing else but a conglomerate of H12C22O11 molecules stacked one over another in layers with van de Waals (?) "forces" keeping them together in a macroscopic state at a temperature of let's say 20 degrees Celsius. Then I use 100 such tiny pieces to throw them in 20 deg water. I stir the...
