Can You Smell That Smell? Post Lab

Can You Smell That Smell? Learning Objectives Learn how to heat chemicals safely Learn how to work with dangerous chemicals safely Be able to identify alcohol, ester, and carboxylic acid functional groups Begin to learn how to write down chemical reactions

What you need to do (Must be typed) Write out the reactions for each reaction you did with appropriate labels (3 of these) Draw the bond dipole arrows on each polar bond for the esters you made Identify Unknowns A and B by their smell and internet research. You must include structure and name. Answer remaining questions

Why do people smell different things when they are smelling the same chemical? Humans have only 5-6 million cells in nose that are set aside for smell … dogs have 220 million … so our sense of smell isn’t as refined … genetic mutation will lead to more disparity in humans then dogs. Our sense of smell is best when we are around 8 yrs old. Smell is something you can practice and get better at. Humans can smell about 10,000 distinct odors.

What was the scent for #3 supposed to be?

What are those stupid stones for? Promotes even boiling … otherwise your reactions might explode out of the test tube.

Why did the sulfuric acid turn paper towel black? When you burn wood the black stuff left behind is carbon …. When you burn paper …..

Why doesn’t sulfuric acid burn through plastic? Sulfuric acid is a polar molecule that dissolves in water. Glass and plastic are molecular non-polar compounds that are water insoluble. Sulfuric acid needs to dissolve in order to be acidic.
