Discussion Overview

The discussion revolves around creating a ball and stick model of sodium para-dodecylbenzene sulfonate, focusing on the structural representation of the molecule and the appearance of the dodecyl group. Participants explore the relationship between structural diagrams and physical models, as well as the specific characteristics of the dodecyl chain.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification, Homework-related

Main Points Raised

  • One participant questions whether the ball and stick model matches the structural diagram of sodium para-dodecylbenzene sulfonate and expresses uncertainty about the appearance of the dodecyl part.
  • Another participant suggests that the structural diagram may not adequately emphasize the molecule's structure and admits uncertainty regarding the assignment's requirements.
  • A participant describes the dodecyl group as a long chain alkane attached to the benzene ring, noting the repeating (CH2)10 units and clarifying that carbon typically forms four covalent bonds.
  • One participant shares their approach of adding a long chain to their model and expresses concern about its appearance, asking if others have seen similar models.

Areas of Agreement / Disagreement

Participants express varying levels of uncertainty regarding the structural representation of dodecyl and the overall appearance of the ball and stick model. There is no consensus on the best way to represent the dodecyl group or the adequacy of the structural diagram.

Contextual Notes

Participants mention the need for clarity in structural diagrams and the specific bond angles, but these aspects remain unresolved. There is also a lack of definitive images or references for the dodecyl group.

How Do you create a ball n stick model of dodecylbenzene

Does the ball n stick model of a molecule match its structural diagram, and how?:confused:this is the structural diagram I'm using for sodium para-dodecylbenzene sulfonate

And this is what my Ball n stick model looks so far, I'm missing the dodecyl part because I'm not sure how it looks like, i tried google but it didn't give me any good images of it. (srry for the low quality pic, its was the only way i could upload it:frown: )

Does ne1 know?:rolleyes:
 
that's probably not a very good structural diagram, you've got to emphasize the structure of every aspect of the molecule. However, I've got to admit that I'm not quite sure about the exact nature of this assignment.
 
i'm supposed 2 create a Ball n Stick model of sodium para-dodecylbenzene sulfonate, but I'm not sure how dodecyl looks like. I know benzene has a hexagonal shape but I'm not sure how dodecyl would look like.
 
I think its just a long chain alkane attached on the end of you benzene ring there.

The (CH2)10 repeating alkane occurs 10 times, hence decyl ( a little confusing if you think it can form a dodecahedron, however remember carbon generally only forms 4 covalent bonds and this one has 2 hydrogens already attached and is linked in a chain ).

.../\/\/\/\... is usually the shape you get, you can look up the specific bond angles if you like, its roughly 2/3Pi i think and the hydrogens would poke in and out of the plane at 120deg to the carbons.

The p- in the chemical name gives you a clue to the how the groups attach to the benzene ring.

i think that how it looks...
 
ye thanks 3trQN that's what i did, i added a long chain that looks like /\/\/\ n i added 2 hydrogens to each carbon but it looks soo odd , has any1 ever seen a ball n stick model that looked like that (see above pic and imagine a chain of carbon with little hydrogens on top of each attached to the benzene ring that looks like /\/\/\/\/\) , if so please let me know.
