Question

please help! correlation of acidity with electrostatic potential. The assigned acid is Maleic Acid: Electrostatic Potential is 379.2 kJ/mol. Answering any part of this assignment would help greatly to understand more about it.

Assigned Acid #27 03 02 04 01 C2. H3 H2 Maleic Acid - Electrostatic Potential is 379.2 k]/mol Kal = 1.2 x 102 1. Using the Electrostatic Potential Map word document posted on Moodle, identify the region(s) with the most positive electrostatic potential of your assigned acid and explain why that region is the most positive. You must be specific with your regions by using color and atom numbers like C1 or C2. 2. Using the Electrostatic Potential Map word document posted on Moodle, identify the region(s) with the most negative electrostatic potential of your assigned acid and explain why that region is the most negative. You must be specific with your regions by using color and atom numbers like C1 or C2 Data for graphing pKa with Assigned Acid 3. Calculate the pKa for your assigned acid using the given K. Show all your work for credit. 4. Graph the maximum electrostatic potential given for each molecule vs strength of the acid as represented by its pKa value using XY scatter plot Table 1). Make sure to label your acid Table 1 Acid Hyrdocyanic Acid Phosphoric Acid Acetic Acid Chloroacetic Acid Dichloroacetic Acid Trichloroacetic Acid Your assigned Acid Strength Weak pKa 9.2 Weak pKa 1.3 Weak pKa 4.8 Weak pKa 2.9 Weak pKa 1.5 Electrostatic Potential 262.3 kJ/mol 368.5 kJ/mol 295.5 kJ/mol 337.7 kJ/mol 356.1 kJ/mol Borderline pKa 0.3 375.6 kJ/mol Weak pKa-use your Use value on page 1 calculated pKa from #3 5. In 3 to 4 sentences, explain why there exists a correlation between electrostatic potential and acid strength? Does your assigned acid follow this trend or does it appear to be an outliers? Explain. 8. Draw the Lewis structures for the acids on the next page. Make sure to follow Show all lone electron pair and Geometry Around Central Trigonal Planar, or Bent all the direction given in the table Lewis Structure Acid bond orders. Circle the acidic hydrogens Show resonance structures when appropriate Atom(s): Tetrahedral, N Atom O Atom (Connected to H): Nitric Acid HNOs C Atom (Connected to H's): C Atom (Connected to O's): Acetic Acid CH3COOH O Atom (Connected to H): C Atom (Connected to H's) C Atom (Connected to O's) O Atom (Connected to H): Fluoroacetic Acid CH2FCOOH C Atom (Connected to H's): C Atom (Connected to O's): Difluoroacetic Acid CHF COOH O Atom (Connected to H): C Atom (Connected to F's): C Atom (Connected to O's): Trifluoroacetic Acid CF COOH O Atom (Connected to H):
