Problem 9
What makes something smell the way it does? Discuss your own hypothesis about why different things smell different. Include questions you still have.
Problem 9
Which is more likely to exist in nature, a molecule of \(\mathrm{CH}_{3}\) or a molecule of \(\mathrm{CH}_{4} ?\) Explain your reasoning.
Problem 11
What are isomers?
Problem 12
If you are given a structural formula of a molecule, do you also know its molecular formula? Explain your thinking.
Problem 13
The words isotope and \(i\) sosceles also have the prefix "iso-" How are their meanings similar to that of the word isomer?
Problem 15
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 18
Explain why one molecular formula can represent more than one structural formula.
Problem 19
Use the HONC 1234 rule to create possible structural formulas for molecules with these molecular formulas. Remember that it is easiest to start with the carbon atoms. a. \(C_{3} \mathrm{H}_{8} \mathrm{O}_{2} \quad\) b. \(\mathrm{C}_{4} \mathrm{H}_{11} \mathrm{N} \quad\) c. \(\mathrm{C}_{4} \mathrm{H}_{10} \quad\) d. \(\mathrm{C}_{5} \mathrm{H}_{12} \mathrm{O}\)
Problem 22
How are an ionic bond and a covalent bond dif erent? Similar?
Problem 23
What is a Lewis dot structure? Explain how you would create one.
