- Be sure to answer all parts. Draw the products of the following acid-base reaction. CH3 CH3 + H₂SO4 - draw structure ... conjugate acid H O O edit structure ... conjugate base3. Multiple Choice: Which acid has the lowest pKa? (Hint.. Question Which acid has the lowest pKa? (Hint: Drawing the structures may be helpful.) Answer А.CHзCO2H B.CICH2CO2H С ВгCH2C02H D.CICH2CH2CH2CCO2HPut the following compounds in order from weakest acid to strongest acid. Explain (pKa values are not enough and trends should be considered).
- explain in great detail why the pKa values are what they are and compare them among the three compounds. The conjugate acids that are protonated are drawn in red for each compound. Which one based on the pKa is most acidic and what does that tell you about how basic their lone pairs are?The pka values of OH group in 4-cyanophenol and 4-nitrophenol are identical BUT in the di-metbylsbstituted compounds C and D differ significantly. The cyano derivative C is more acidic than compound D. Please briefly explain why this is the case (you can use words and drawings). Hint: delocalization...
