1. Identify the most acidic proton in each molecule. Briefly explain your reasoning based on structure (stating the pKa value is not enough, here. You must bring in factors related to ARIO). OH HACO NO2
For each molecule below, predict the most acidic proton. Explain your answer in each case.
1) Draw the conjugate base of each acid by deprotonation of the
most acidic proton (might not be shown).
2) Rank the following acids from weakest to strongest (1=weakest
6=strongest)
ОН (А) ГОН "NH₂
Predict which proton would be more acidic and explain your
reasoning.

o orale a. Underline the most acidic hydrogens in each of the molecules. b. Rank the molecules above in order of increasing acidity (least acidic to most acidic). a. b. III, II, II, III, I d. II, 1, 5. Nitroethane [CH3CH, NO, PK, 8.6) is a much stronger acid than ethane (CH,CH.PK, 60). Explain. Consider the reaction below to answer the following question(s). pk = 26 pk = 40 0 L : Lit L H . YHLUN -...
Which alpha proton in the molecule below is the most acidic? d C toitevi Zoom B А B D C
Predict which proton in ascorbic acid is the most acidic.
Identify the appropriate atom by selecting each atom and
assigning it a map number of 1 until all atoms are mapped. To do
this, right-click on an atom and choose Atom Properties. (Mac
users: Use an equivalent for right-clicking.) Then, clear the
check mark to enable the Map field before entering a value.
Draw the form of ascorbic acid that is present in the body
(aqueous solution, pH = 7.4)....
9. For each of the following pairs identify the strongest Bronsted base and explain you reasoning (your answers should be based on the acidity of the conjugate acid. For example in (a) what is the conjugate acid of NH2- and how does it compare with that of OH-? Keep in mind the following : 2NH3(1) = NH4 + NH2, K = 10-30). (a) NH2- or OH, (b) 02- or S2- (optional extra credit) (c) ClO2 or ClO3
Which alpha proton in the molecule below is the most acidic? a d с A B С D
2) For each of the acids, indicate which proton is more acidic, A or B. Circle the more acidic proton in the structure. Explain your reasoning in one or two sentences (no more!) using a conjugate base stability argument. a. A Fo НО. OH B b. A -H NOH B
