Dimethyl Sulfoxide - Molecular Geometry: The 3D Molecule

Molecular Formula: (CH3)2SO



Key:

Red: Oxygen
Yellow: Sulfur
Gray: Carbon
Silver/Dark White: Hydrogen


The arrows help provide a visual representation of the electronegativity of the atoms. The arrows always point from the less electronegative atom to the more electronegative atom. For example, one arrow points from sulfur to oxygen. Sulfur has an electronegativity value of 2.6, while oxygen's electronegativity value is 3.5. The higher the electronegativity value, the more electronegative an atom is. So, the arrow points from sulfur to oxygen.

  1. General Appearence:
    This appearance of this blog it very clear to read all the information, and is a very practical and useful layout.

    Accuacy of Model:
    The model in the blog is perfect. It shows how each angle is measurd carefully and also shows the arrows ponting to the higher electronegativity.

    Polar vs Nonpolar:
    In the blog, is is also correctly stated that the molecule is polar. This is becuase of the ineaven distribution of electrons.

    Intermolecular Forces:
    In the blog the intermolecular forces are stated to be London force and Dipole Dipole. This is because the London force occurs for all molecules, and since the molecule is polar, the dipole dipole force is put into effect.

    Efectiveness of Ad:
    Overall, I am motivated to buy this chemical if i was suffering from a urinary bladder disease. Also it is very good how it can protect me from interfering reaction.

  2. The appearance of your blog is mind-boggling. It really catches my attentions and I love the choice of color. Your picture of your molecule is stupendous! It is accurately shown and includes arrows that are right-on. I definately agree with you when you say DMSO is a polar molecule. Your math and explanation can really explain to others why. From my knowledge, the intermolecular forces you listed are 100% correct. You can tell that you spent a lot of time and effort on figuring out which forces are actually evident. Man oh man! Do i want some DSMO! Your ad really makes me want to buy some with it's logical uses. I think I might try to purchase some actually...Overall, BRAVO!

  3. Appearance:
    The blog is very organized and neat. I also like the background of the blog because it is very nice and make the blog interesting.

    Drawing:
    The drawing is perfect. It is very accurate and easy to look at. Also, the arrows are drawn right and are very helpful.

    Polarity:
    The blog accurately states that the molecule is polar.

    Forces:
    The blog is correct in saying that the molecule has both London Dispersion forces and Dipole Dipole. Also, it has a great explanation and the picture which shows the Dipole Dipole attraction makes it easy to understand.

    Advertisement:
    This ad is very convincing. It really makes me want to buy DMSO. Also, i love the creative wording in the ad, it can make anyone want to buy DMSO.

  4. Appearence:
    The overall appearence of the blog is nice and organized. The background is creative. All the posts are organized and it helps to understand the blog better.

    Accuracy of drawing:
    The drawing is very good. It properly shows all the atoms and the arrows that show the electronegativity of the atoms. The drawing is very neat which makes it easy to understand. Also, the description is very helpful and leaves the reader with no questions after viewing the model.

    Polarity:
    The molecule has been correctly identified as polar. This is because there is an uneven distribution of the electrons throughout the molecule.

    Intermolecular Forces:
    In the blog it is accuratly stated that both the London dispersion force and the dipole dipole force occur in this molecule. The explanations given for the forces are descriptive and helpful.

    Advertisement:
    This ad is very convincing. It is very helpful to know that this chemical can remove paint and treat bladder diseases. The phone number at the bottom is very creative.

  5. The appearance of your blof is great although i feel like you could have used a little more vibrant colors to draw attention to certain things you wanted to emphasize. Your organization and strucutre is great and it is easy to tell what you are looking at. The drawing is excellent and gives me a great represenation of your molecule. The colors allow me to see which atom is which and the 3-d aspect is also excellent. You said that your molecule was polar and by doing so you are correct because there is in fact an uneven distribution of electrons in your molecule. You're intermolecular forces stated in your bloga are also on point and again gives me some very useful information about your molecule. Lastly, your advertisement is very convincing and at the same time is to the point and tells the customer what your chemical is useful for. Excellent job Kevin!
