Discussion Overview

The discussion revolves around the number of isomers for the chemical compound C4H9Br. Participants explore the structural representations and classifications of isomers, including considerations of enantiomers and structural similarities.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant claims there are 5 isomers for C4H9Br, providing specific structural representations.
  • Another participant argues that two of the proposed structures are identical, suggesting that they represent the same isomer (2-bromobutane).
  • A different participant asserts that there are only two isomers, without providing further details.
  • There is a mention of enantiomers, with a participant noting that they do not consider them as isomers in this context.
  • Participants express uncertainty about the correct representation of chemical structures and suggest using chemical drawing software for clarity.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the total number of isomers for C4H9Br, with differing opinions on the count and classification of the structures presented.

Contextual Notes

There are unresolved issues regarding the identification of isomers and the potential for enantiomer formation, as well as limitations in the clarity of structural representations due to formatting challenges.

The book says 4, but isn't there 5?

1) CH3-CH2-CH2-CH2-BR

2) CH3-CH2-CH-CH3
BR

3) CH3-CH-CH2-BR
CH3

4) CH3-CH2-CH-BR
CH3



CH3
5) CH3-C-CH3
BR



ugh..sorry i can't get the computer to place the atoms in the right place, but u guys get the picture

I think 2 and 4 are the same... Both can be read as 2-bromobutane, please look at them carefully, you'll see. I don't consider enantiomer formation, as there should be 2S-2-bromobutane and 2R-2-bromobutane, because they are not isomers, enantiomers, i.e., optical isomers.

About drawing formulae, I am not sure, but our moderator can show us how to arrange LateX to draw these formulae. It is possible, I know. If it isn't, it would be better for you to obtain some freeware chemical drawing software like ChemSketch or Isıs-Draw.

it have only two isomers
 
Thankyou!

THANKYOU!
:):approve::smile::smile::!) your a real o:)
this was a lot of help!
