Discussion Overview

The discussion revolves around the nature of functional groups in organic chemistry, specifically questioning why organic compounds cannot be separated from their functional groups and what characteristics define these groups. Participants explore the implications of functional groups in reactions and their hierarchical importance in organic compounds.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants wonder why organic compounds cannot be separated from functional groups, contrasting this with inorganic compounds.
  • There is a suggestion that certain inorganic ions act as functional groups and a question about what distinguishes them from other inorganic ions.
  • One participant proposes that functional groups are parts of organic molecules that exhibit consistent properties regardless of the larger molecular context.
  • Another participant notes that the reactivity of functional groups is significant and that their properties can be somewhat independent of the carbon framework they are attached to.
  • Clarifications are sought regarding the term "separation" and the context of organic reactions involving functional groups.

Areas of Agreement / Disagreement

Participants express varying degrees of understanding and interpretation of the role and nature of functional groups, with no consensus reached on the initial questions posed by the original poster.

Contextual Notes

Some participants express uncertainty about the terminology used (e.g., "rbf") and seek clarification on the original questions, indicating potential gaps in understanding the discussion's context.

I have Been wondering a lot that why we cannot separate the organic compounds from the functional groups. And this is not established by the inorganic compounds!

What looks strange to me even more is that whenever a reaction occurs we face the functional group and these functional group are even in an orderly protocol of dominance!
Is there energy associated with these functional groups? and if yes? what makes so?

Please elaborate - what do you mean by 'separation'?

I can't answer OP's question, but I think I can clarify (key word is think) so that someone with a little more knowledge can give an answer. I think OP meant why do certain inorganic ions (OH-, NO2-, etc) act as functional groups, i.e. what separates them from other inorganic ions? And what determines their priority when substituting them onto a hydrocarbon (OH replacing a halogen for example)?

I could be wrong, but this is what I got from OP's questions. I'm actually pretty interested in hearing a response too, since I haven't studied organic chem in detail. I realize this is probably not a simple response type question, but if someone has a link or something, I would appreciate it.

Well, fundamentally: Not much. But it depends on the context. For instance, an organic molecule with a basic group might not be able to participate in a base-catalyzed reaction because it's sterically hindered by the bulky organic part.

But in general, the point of functional groups is to identify parts of organic molecules that are relatively independent. That have more-or less the same properties no matter what organic molecule they're connected to, and so you know that a reaction or property of one functional group will normally be the same everywhere. Obviously not everything qualifies as a functional group. Is "=CH-" a functional group? Well, no, because there's a big difference whether it's part of propylene or a benzene ring, for instance.

And what determines their priority when substituting them onto a hydrocarbon (OH replacing a halogen for example)?

Wow! This question has it all! Dominance, energy, separation, protocol, order, functional groups... Too much to take in all at once.

Dude, Shulgin is not your friend.
 
for the most part, if you have a compound in an rbf with a bunch of like NaOH, you'll have an organic layer and an aqueous layer, so things separate naturally...

not really sure what your question is though... can you rephrase?

May be I should say it this way.
Whenever organic reactions take place, we always face the functional group. Then what's really special about these functional group?
Hows there!

Excuse me!
i don't really get you. What do you mean by rbf!
And seriously I haven't undrestood you well in you former thread.

They are the most reactive parts of the organic molecule, and their properties are - to some extent - independent on the carbon framewrok they are attached to.
