The ranking of the conjugate bases in terms of increasing base strength. 5.A justification for the rankings based on the factors that influence the relative stability of the different conjugate bases. I need to answer these for C3H5ClO2, ClCH2CO2, and CH3COOH. (Acetic acid, 3-chloropropanic, and chloroacetic acid). Pleaseeee help I will definitely ratearrow_forward1. Cl2 2. 3 equiv. NaNH2 3.

Consider each reaction below carefully. Identify the acid and base on the reactant side of the reaction. Draw the expected product of a proton transfer between the acid and base. Estimate the pka of the acid and conjugate acid. Determine whether the reaction is product or reactant favored. a. b. C. d. OH @O HICI HO NaH 39arrow_forwardC341 Chapters (Acid-base chemistry) 9.) Acid-base equilibrium. For each reaction, perform the following tasks: a.) Complete the following reactions using the appropriate curved arrows to demonstrate the flow of electrons pairs in each potential reaction. b.) Indicate if the reaction lies to the right or the left (circle the correct arrow direction). c.) Calculate an approximate Ken for each reaction. d.) Write the pKa values under each acid, so we can evaluate your progress better and award partial credit. d.) Finally, label the acid (A), base (B), conjugate acid (CA) and base (CB) correctly based on the direction you decided.

- 3. The pKa1 and pKa,2 of ortho and para isomers of phthalic acid (diprotic acid) are shown below: pKa1 pKa2 phthalic acid terephthalic acid 2.98 5.28 3.51 4.82 CO2H CO2H HO2C phthalic acid terephthalic acid Provide an explanation on the differences of their pKa values.arrow_forwardI mostly need help setting up how to do the math for these problems. I also need help with knowing how to find which acid is the strongest. Give the Ka or pKa values that should be entered in the blanks below. pKa = -log10ka ; Ka = 10-pKa (a) hydrocyanic acid: Ka = 4.92 x 10-10 ; pKa = (b) acetic acid: Ka = ; pKa = 4.75 (c) lactic acid: Ka = 8.40 x 10-4 ; pKa = (d) formic acid: Ka = ; pKa = 3.75 (e) Which of these acids is the strongest?arrow_forwardUsing the HSAB theory, predict the direction of the ff. reactions and explain. a.
