Do you love that nice odor of vinegar, the usefulness of plastics and rubber, and those handy nonflammable film reels?

Then get yourself some Acetic Acid!
It's the best stuff in town!


It's uniquely shaped:
 The carbon bonded to three hydrogens and the oxygen bonded to carbon and hydrogen are 
Tetrahedral Structures (AX4):
these have 109.5 degree bonding angles

The second carbon atom is 
Trigonal Planar (AX3):
these have 120 degree bonding angles

Around the oxygen is 
Bent (AX2E2):
these have 109.5 degree bonding angles

Here it is in 3D, notice the double bond between the Carbon and Oxygen:



It even has some super strong intermolecular forces... 
guaranteeing some great bonds!

Of course like all molecules that bond, Acetic Acid has 
London Dispersion: as electrons move around atoms, they may be more to one side than another, very temporarily.  It is the weakest force.

Since this molecule is polar, it also has 
Dipole-dipole: stronger than dispersion, dipole happens when one end of the molecule is negatively charge and one end is positively charged. 

This molecule is really a special one because it also has
Hydrogen Bonding: even stronger than dipole, this bonding occurs when a Hydrogen of one molecule is attracted to the O, F, or N of a nearby molecule. 
*If it were to bond with itself one of the many hydrogen atoms could bond with an oxygen atom


Electronegativity 


C=2.5
H=2.2
O=3.5


 C and H -- .3 (Moderately covalent)
    H and O -- 1.3 (Moderately covalent)
C and O -- 1 (Moderately covalent)


Acetic Acid is very useful, but very corrosive, 
don't get it on you!


Fun Facts about Acetic Acid:
  • It is the simplest carboxylic acid
  • Melting Point: 16.6 C
  • Boiling Point: 117-118 C
  • It is a clear liquid at room temperature
  • It is used in the production of  
                       -food
                       -cosmetics
                       -rubber chemicals
                       -flavor fragrance
                       -vitamins
                       -antibiotics
                       -developing film

As you can see this molecule is widely used, whether you are keeping healthy, getting ready in the morning, want a tasty snack, or preserving some cherished memories Acetic Acid is everywhere!

Surely you can't live without it so get some today!

  1. Overall, the appearance of this blog really catches my eye. The use of all of the colors and strategically placed pictures add a nice visual. The colors of the words distinctively show the different sections of the blog. There does not seem to be too much writing or too little.

  2. You seem to be correct in saying the bond angles are showing which degrees corresponds to which shape. Although comparing the Lewis Structure model to the 3D model, the shape is correct but from my understanding, this molecule does not have a specific central atom. Without a specific central atom, the molecule is just linear. Is it possible that this molecule has more than one central atom? Also, you seem to have forgotten the polarity of the bonds by using the arrows and did not clearly represent the positive and negative ends of this molecule (using a + or -).

  3. You are correct in saying that is has 3 forces of attraction. Since the molecule is polar, it will have a dipole-dipole force if it were to come across the same molecule. Since there are hydrogen atoms and oxygen atoms, there would be hydrogen bonding also if it came across the same molecule. And of course, like all molecules, london dispersion forces are also available.

  4. Although you did state that the molecule is polar when talking about the forces of attraction, I feel you could have explained it more. You may have wanted to talk about why it is polar. What makes this molecule polar?

  5. Your ad seems to be effective. Acetic Acid seems to be involved in the production of many common necessities. How deadly is it to swallow though? What are the safety risks involved with this molecule. How much would this roughly cost? Is it common to have around the household? If we are too exposed to this molecule in our daily lives will it eventually lead to problems and possibly cancer when we are older?
