Interpret and match the given potential map with molecule containing Cl and F and other containing P and F along with the molecular formula. Concept introduction: The electrostatic potential map is the representation of the atoms present in a molecule carrying partial positive or negative charges on them. The atom carrying higher positive or negative charges are shown with the darker color in the potential map. The intensity of the color in the potential map is the indication of the amount of charge the atom carrying on it. For example; the electrostatic potential map for chloromethane is shown as: The color code for the atom present in a given molecule carrying higher positive charge is violet or dark blue while the color code for the atom present carrying higher negative charge is orange.

Calculating the pH of a weak base titrated with a strong acid
An analytical chemist is titrating 184.2 mL of a 0.7800M solution of dimethylamine ((CH3)
NH with a 0.3000M solution of HClO4. The pK₁ of
dimethylamine is 3.27. Calculate the pH of the base solution after the chemist has added 424.1 mL of the HClO solution to it.
