Lewis Structure

The Lewis Structure for N2H4, with each pair of electron bonds circled in red.

  1. Amanda,
    I really like how simple the whole blog looks, the dark turquoise and white makes it seem clean and simple, yet bold. It gives a little color to something that may not be too exciting. I also like how you set up your posts with not a lot in each, but a lot of posts, it makes it look separated and then you’re not reading too much all at once. The use of pictures is also really good, as it gives a lot more of a visual. The only thing is that some of the pictures for some reason seem to be going over the edge and not in the middle.
    The drawing of the Hydrazine molecule looks correct, with the proper angles for a pyramidal structure on both ends. Also the arrows showing the lower electronegativity to the higher negativity are correct as the Nitrogen has a higher level than the Hydrogen. You showed all three forces of attraction which take place between N2H4 and another N2H4 molecule. I like how you made different pictures to show the different forces of attraction, it made it much easier to picture.
    There was only one thing that I could really comment on and that is that although your ad is very informative, it is not immensely convincing. Although, if I ever decide I want some fuel for a rocket, I would definitely be going for some Hydrazine!

  2. I completely agree with the post above me that explained the design of the blog. The somewhat darker turquoise gave the blog a sleek and simple look, which I really liked. The first picture, the picture of the Lewis Structure of Hydrazine, was accurate and very unique to the blog. Most blogs that I had looked at did not have the Lewis Structure. Next, was the 3-D structure of the molecule. This picture was extremely detailed and easy to understand. It accurately showed the arrows symbolizing a lower Electronegativity level to a higher Electronegativity level. Then, it showed the polarity of the molecule. It correctly stated that the molecule was polar and clearly unbalanced. Again, there was a very detailed picture that aided with the explanation. I also like how each bond was accurately explained, telling whether it was non-polar or polar and whether it was covalent or ionic. Not many blogs contained this, so again it showed how much work was put into the project. Next, there were the intermolecular forces of attraction. I agree that all three forces of attraction would take place if two molecules of Hydrazine were placed next to each other. All of three forces were explained thoroughly, which was very helpful. Finally, there was the AD. It contained just enough information, to make it interesting but not to overwhelming. I really enjoyed looking at your blog and you did a great job!!
