Problem 6
Two molecules have the same molecular formula, yet one smells sweet and the other smells putrid. Explain how you think this might be possible.
Problem 6
Try tasting something while having your nose plugged and your eyes closed. You may wish to work with a partner who can provide you with a variety of different flavored jelly beans or other food items to sample. a. Describe your experience. How difficult is it to taste something when you can’t smell it and you don’t know what it is? b. How do you think taste is related to smell?
Problem 6
Use the octet rule to draw Lewis dot structures for all the stable molecules with the molecular formula \(\mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}\) . (Hint: There are three total molecules.)
Problem 6
Ester molecules are named for the alcohol and acid that form them using the convention $$\begin{array}{l}{\text { (alcohol name)yl (acid name)ate }} \end{array}$$ For example, methanol \(+\) ethanoic acid combine to make methyl ethanoate. Name the esters formed from a. isopropanol + methanoic acid b. caproic acid + butanol c. salicylic acid + ethanol
Problem 7
Consider the molecules \(\mathrm{C}_{2} \mathrm{H}_{2}, \mathrm{N}_{2} \mathrm{H}_{2},\) and \(\mathrm{H}_{2} \mathrm{O}_{2}\). a. Draw a Lewis dot structure for each one. What pattern do you notice? b. What can you do to check that your Lewis dot structures are correct? Name at least two ways.
Problem 7
If you were a chemist and you wanted to invent a new smell, what would you think about doing or creating?
Problem 8
What do you think \(1,5\) -pentanedithiol \(\left(\mathrm{C}_{5} \mathrm{H}_{12} \mathrm{S}_{2}\right)\) would smell like? How confident of your answer are you? Explain why.
Problem 8
If you were a chemist and you wanted to change the smell of a molecule, what might you try to do to that molecule?
Problem 8
Consider the molecules \(\mathrm{C}_{2} \mathrm{H}_{4}\) and \(\mathrm{N}_{2} \mathrm{H}_{4}\) . Draw a Lewis dot structure for each of the molecules.
Problem 8
Draw Lewis dot puzzle pieces for Si, P, S, and Cl. What rule would you make for Si, P, S, and Cl? What would be the name of this bonding rule?
