Today in our lab we represented molecules by making them with gumdrops and tooth picks. We were first given a worksheet with four examples of molecular structures and 18 blank molecules to figure out those structures. We first started recreating picture. The three that we did were aspirin, caffeine, and nicotine. Aspirin is made out of carbon, hydrogen, and oxygen. Caffeine has, carbon, hydrogen, oxygen, and nitrogen. Lastly nicotine has, carbon, hydrogen, and nitrogen. The gum drops were to represent each atom and the tooth picks were to represent the bonds between them.
There were multiple aspects that I learned from this lab. One thing that I found quite interesting was why the electrons had to be placed as far away from each other. The reason why that is because they repel each other. When making these structures it was important to spread them apart as much as possible. Something else that I noticed was to include hidden carbon and hydrogens. Most shapes of the molecules had the shape of a hexagon. The reason why that happens is because every peek or point of each bond fills in as a carbon. Like I said before another shape that was interesting was the molecules that were a straight line (them being far apart from each other).
