Naming Organic Compounds: IUPAC Naming

Click For Summary

Discussion Overview

The discussion revolves around the IUPAC naming of organic compounds, specifically focusing on the correct nomenclature for the compound CH3CHBrCH2ClCH2. Participants also explore whether CH3OCH3 can form a hydrogen bond. The scope includes theoretical aspects of organic chemistry nomenclature and the application of IUPAC rules.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant questions whether the compound should be named 3-bromo-1-chlorobutane or 2-bromo-4-chlorobutane.
  • Another participant emphasizes the importance of showing work and reasoning behind the proposed names.
  • A participant mentions that numbering the carbon atoms can lead to different interpretations, raising the question of which numbering method is correct.
  • One participant recalls that IUPAC nomenclature requires functional groups to have the lowest sum and should follow alphabetical order, seeking confirmation on this rule.
  • Another participant provides a visual representation of the compound and suggests that it appears to be 3-bromo-1-chlorobutane based on their perspective.

Areas of Agreement / Disagreement

Participants express differing views on the correct IUPAC name for the compound, indicating that there is no consensus on the naming conventions being discussed. The question of whether CH3OCH3 can form a hydrogen bond remains unaddressed.

Contextual Notes

Participants have not fully resolved the assumptions regarding the numbering of carbon atoms and the application of IUPAC rules, which may affect the naming outcome.

IUPAC naming!

Hey folks,
I just wonder how would you name this compound
CH3CHBrCH2ClCH2
is it 3- Bromo -1- chloro butane
or 2- bromo 4- chloro butane
another question : does CH3OCH3 form a hydrogene bond or not?
Any help would be greatly appreciated

You need to show your work.

What do you think the answers are and why?
 
well actaually i did the work ... and i am confused between the answers that i wrote ... wut i did is numbered the carbon atoms ... well i can number them in two different ways ..one where i will get the bromo on the 2nd atom and the chloro on the forth atom , and the other way is to number them where the bromo on the 3rd atom and the chloro on the first .. my question is which of numbering is correct .. ?
 
?

If I remember correctly, The nomenclature in which the functional groups get the lowest sum is to be used. Also, you should follow alphabetical order while naming them.
I am not too sure on this, so if I can get conformation, it would be nice.
 
I don't know if its a bit late but think about it.

IUPAC names it in alpha order and to the lowest sum.

Your compound looks like this:
| | | |
-C-C-C-C-
| | | |
Br Cl

Which would you think it looks like? From my perspective, it looks 3-bromo-1-chlorobutane.
