please show all work thank you im advance

Experiment #5-Acidity and Electrostatic Potential Experiment #5: Correlation of Acidity with Electrostatic Potential This Experiment is Done in Groups of 2 Background: his laboratory experiment is focused on theoretically predicting the acidity of several molecules. A software package called "Spartan" was used to predict the structure electrostatic potential of each molecule. The electrostatic potential at a point P is defined as the Coulomb energy of interaction between the electron-charge cloud of the molecule and a positive point charge placed at the point P. The electrostatic potential can be used to distinguish regions that are electron deficient from those that are electron rich. A positive value of the electrostatic potential at point P indicates that the positive charge is repelled by the cloud. Such a condition occurs when an area is deficient in electron density. A negative electrostatic potential value at point P indicates that the positive point charge is attracted to the cloud. Such a condition exists with the area has excess electron density Molecules that are strong acids should have a highly positive electrostatic potential near their acidic hydrogen(s). This leads to a repulsion of the hydrogen nucleus (i.e., the proton) that will cause it to be more easily transferred to molecules that can act as bases. In this laboratory experiment, you will use the Spartan program videos to determine the electrostatic potential of the hydrogens on an assigned acid along with the most positive and negative electrostatic potential. You will also be drawing the Lewis structures for several molecules You will then be asked to explain on the link between molecular structure and electrostatic potential and the link between molecular structure and acidity. Each student is strongly encouraged to review the information in their General Chemistry textbook regarding molecular structure (e.g., Lewis diagrams, VESPER structures, etc.) and its impact on acidity prior to performing this experiment. Assigned Acid #8 H1 o1 02 Chlorous Acid-Electrostatic Potential is 406.5 k]/mol K, 1.1 x 10-2 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 o C2.
