This molecule is very helpful. It is slightly reactive towards water. It is considered a "iodination reagent." It can be used to create the chloride in alcohols. This involves alcohol-based hand sanitizers. Adding chloride to the alcohol is what enables it to kill germs and bacteria. CI4 helps to keep you healthy.
Caring for your CI4
It is soluble in nonpolar, organic solvents.
It is advised to be kept at 0 Celsius.
Also CI4 is an irritant, so handle with caution.
General Appearance:
ReplyDeleteThe layout of the blog is very organized. The subtitles of each post allow the reader to find exactly what they are looking for, and know what they are reading. The background is also very nice, because it ties in with the whole theme of chemistry.
Accuracy of Molecule:
ReplyDeleteThe 3-D model of the molecule is very accurate. It shows the correct angles, and is color coded to help the viewer to easily identify each atom. The correct polarity is shown. You are able to see how the carbon atom is more positively charged, and how the electronegativity of the atom moves away from the central carbon atom.
Polar vs. Nonpolar:
ReplyDeleteIt is correctly stated that this molecule is nonpolar. It is nonpolar, because the electronegativity is evenly distributed throughout the molecule.
Intermolecular Forces:
ReplyDeleteThe only intermolecular forces acting upon this molecule are london dispersion forces. This attraction can occur between any two molecules, and this was correctly stated and explained on the blog.
Effectiveness of Ad:
ReplyDeleteOverall this ad was very effective. It summarized the general make up of the molecule and what it could be used for. The diagrams and information presented were accurate. The actual chemistry makeup of the molecule, such as is shape and polarity were correct, as well as, the intermolecular forces that act upon the molecule. The ad was clear, and looked nice.
Overall Appearance:
ReplyDeleteThe blog is well organized. However, the information in the blog is at times difficult to read because of the multi-colored background. Besides that, the blog is excellently prepared.
Accuracy of the Model:
The model is accurate. The key for the model also accurately identifies the types of atom in the molecule. The electronegativity is also correctly displayed through the arrows pointing to the more electronegative atom. My only complaint is that the lighting of the photograph makes the iodine atoms look red, not orange.
Polarity:
The molecule is correctly stated to be nonpolar, due to the equal distribution of electrons throughout the molecule. I have two comments. The first, somewhat fastidious, comment deals with grammar. In the polarity section of the blog, "If it was polar" should read "If it were polar." In addition to this grammatical error, the section says that the "force" is evenly distributed throughout the molecule. I think a better term for "force" is "charge."
Intermolecular Forces:
The blog also correctly states that London dispersion forces are the only intermolecular forces acting upon carbon iodide. The force, due to the constant motion of electrons around two atoms, forming a temporary dipole, is correctly explained and described. I think the blog should emphasize, though, that London dispersion forces occur between any two molecules.
Effectiveness of the Ad:
I think the ad is effective. The ad explains the various uses of the molecule. I only wish that the ad went into more detail in regards to caring for carbon iodide. What are some examples of nonpolar organic solvents? Why must carbon iodide be kept a temperature of 0˚C? The ad's effectiveness would be greatly enhanced if more detail was given.
Appearance:
ReplyDeleteThe blog looks great with the background but I feel that it does make the information a little hard to read.
Drawing:
The drawing is accurate. I also like how the model was made out of playdoh because it gives a very accurate image of how the model really looks.
Polarity:
It is accurate to say that the molecule is non-polar. I also like how the polarity is explained in a very accurate way.
Forces:
It is correct to say that the only intermolecular force in the molecule is London Dispersion force. Also, this force is very accurately explained.

The ad is very good at telling what this molecule can be used for. But, I feel that the ad does make somethings a little confusing. Like when the term "iodination reagent" it would be easier if this term was explained.
