1) Predict relative acidity. Rank in order of increasing acidity (be able to explain): a) CH3CH2SO3H, b) CH3CHClCO2H, c) CH3CH2OH, d) ClCH2CH2CO2H, e) CH3CH2CO2H 2) Predict relative acidity. Rank the following in order in increasing acidity: NH3, H2SO4, CH3OH, CH3CO2H, H3O+, H2O Hint: think of what would produce the most stable species after deprotonation. A good acid would gladly lose a proton (to form a stable conjugate base). 3) Predict relative basicity. Rank the following in order in increasing basicity:...

1. (6 pts.) Rank the following compounds in order of increasing acidity. Each series should be considered separately. Use resonance and/or inductive effects to explain acidity. For full credit you will need to draw any resonance forms or indicate dipole if it is relevant. Also for each compound draw its conjugate base. Series 1: OH он OH O Series 2: CN 2. (4 pts.) Fill the reactions with the products and circle the favorite side: OH+...

Order the hydrogens for each molecule in the order you would expect to observe the peaks (upfield/downfield) for 3-methylbutylacetate, 3-methylbutanal, 3-methyl-1-butanol. Report the peaks as you see them for the proton NMR using the tables below: Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Compound: Peak shift mulitplicity Assignment Look at the 13C-NMR and list the peaks and assign them to the carbons in each. What similarities did you notice with the NMR peaks in the three compounds?...

LABORATORY 8 Post-Lab 1. Explain how each of the following errors would have altered your results. Clearly explain why your calculated answer would be high, low, or unchanged. (A single word answer is not acceptable.) a. You decided to take the pH after each addition of 5.0 mL of NaOH rather than after every 0.5 mL during the neutralization of your acid sample. b. While using the Half Volume method, your solution was dark pink (you overshot the endpoint) and...
