Hydrazine

N2H4 is an inorganic chemical compound. It is a colorless flammable liquid that is derived from the same manufacture as ammonia.



Above is a three dimensional model of the molecule N2H4. The arrows depict the the natural flow of polarity from the lower energy level to the higher energy level. The white represents the Hydrogen atoms while the blue represents the nitrogen atoms


Polarity Energies:

H
N
2.2
3.0



As shown in the model above, the arrow goes from the lower electronegativity level, the Hydrogen, to the higer level, the Nitrogen.




N
N
3.0
3.0



In the model above there is no arrow between the Nitrogen because the bond between them is absolutely covalent, meaning the energy can not go from the lower to the higher, so it is balanced.

I liked your blog, it was thoughrough. The appearance catches the eye. I liked your use of the gadgets as well as the post order. It was clear reading except for the title could have been a bit larger. The structure looks right however to me it seems that one part of the molecule should be turned a bit more to make it symmetrical, but I could be wrong. Also I would have liked it more if you showed unshaired electron pairs. Yes I agree that it is polar. I like the fact that you have the electronegativity values and nature of each bonds. I really liked the unshaired electron pairs in your dash model. Intermolecular forces are right, however i believe you are missing the word "around" in you London Dispersion definition. As well as I would have liked to see you mention in the H2 bonding that those bonds break and reform repeatedly. I found your ad very well done as well as quite humourous. "Who doesnt love it [spandex]" Haha. And the small warning label saying its harmful seeing how its rocket fuel was a nice touch.

Your blog has a wonderful overall appearance. It is clean and clear to read, and the blog post order is a logical. Your drawing seems to be accurate, with the arrows are pointing in the right direction. It was nice that you explained why the arrows were there and what they represented. I agree that this molecule is polar, as the unshared electron pairs in the nitrogen atoms makes the electrons unevenly distributed in N2H4. The forces of attraction portion of your blog is correct. You described each briefly, but well. The only thing I could say to change would be to make the hydrogen bonding and the dipole dipole picture separate, although the way you presented it does not appear to be confusing. Your ad is very convincing and funny, as well as informative. The pictures add to the ad and makes the reader want to keep reading. Great job overall!

The overall appearance of your blog is very eye-catching. It appears as though you put much thought into how you were going to arrange your information and your information is extremely well-organized. Also, the information in your blog is very easy to comprehend because you explained yourself tremendously well. All of the pictures of the molecules are accurate and done neatly. The arrows depicting the flow of polarity from the lower energy level to the higher energy level are also correct. I liked how you also stated the polarity energies for hydrogen and nitrogen. I also liked how you provided an explanation under the pictures. You are also correct that the molecule is polar and the forces that attracted these two molecules are also correct. The ad was very persuasive and it contained humor. I really like when you stated “Even the superheroes wear it!” and “However, be warned this chemical is a bi hazardous and quite toxic, so use it with care!” Overall, you blog is very well done and very interesting.
