3-D Model of Ethylene Oxide (Linear)

Electronegativity
H - 2.2
C - 2.5
O - 3.5

Ethylene Oxide is a colorless gas that has a slightly sweet odor. The molecular formula is C2H4O. Ethylene is a linear molecule because the central atom cannot be determined. The arrows show the electronegativity between two elements; more positive towards more negative. Because oxygen has 4 valence electrons that are not bonded, it makes that end of the molecule more negative. All the other hydrogen sides are all positive because they do not have any unshared electrons. Thus, because of the positive and negative ends, this molecule is polar.   

Ethylene oxide was first reported by a French chemist, Charles- Adolphe Wurtz, in 1859. Another name for it is oxirane. Ethylene oxide is considered a cyclic ether. This means that there are two alkyl groups attached to an oxygen molecule in a circular shape. And because of this special structure, ethylene oxide can easily participate in many different reactions because it is able to open up its circular structure and react with other molecules.

Appearance:
I really like the way this blog looks. The little ribbons and color choices are all really nice, and it looks really well put together.

All of the information you have for this molecule is accurate. The blog shows that you know what you're talking about for this molecule, without sounding like a science book.

I agree that this molecule is polar because of the negative O on one side of it, and then the multiple H's, which are much less negative, on the other.

I support all of the intermolecular forces that you listed, and i think you do a good job explaining why each of them are present.

I really like the appearance of the blog as a whole because it catches my eye. The many pictures that are used add to the overall expierience for the reader. The blog is neat and easy to comprehend which is very important!

The Picture of your molecule is accurate and well done. It is neatly put together, and all of the factors such as polar arrows, and unshared electron pairs are present.

I agree with your statement of this molecule being polar. The Hydrogen molecules that bond with the central Carbon molecule have a lower electronegativity and Carbon has a lower electronegativity than Oxygen. All of your arrows are also correctly placed.
