Judging from this experiment, I found out that molecules that look similar, tend to smell similar as well. This can be seen in the worksheet we completed during class. We smelled different odors and tried to figure out what they were. While smelling odor 8 and odor 9, I realized they smelled the same so they must be the same. However, I was incorrect they were two different odors. The reason I thought they smelled the same was because they were structured similar. Odor 8 and 9 were structured almost exactly the same except for the fact that the OH branch was in a different place. Therefore, since the structure was similar the smell was similar as well.
Another reason why I believe molecules that smell similar have a similar structure is because of the way odors 5 and 6 smell. I noticed that like the previous odors I talked about, odors 5 and 6 both are structured similar. They both have structures that include a family of molecules called esters. This is why when we smell these two odors, they produce a similar scent. So in conclusion, when the molecules of two scents are structured the same, they will most likely smell the same as well.
