Name: ______________________________________________ General Chemistry Homework: Section 8.2 Electronegativity & Electron Dot Structure Reference: Table 6.2, pg. 181 in textbook for Electronegativity Values Per: _______ Dr. L. O’Reilly Question I. For each of the following pairs of atoms: a) Draw an arrow to designate the direction to which the electrons participating in the covalent bond are pulled and b) Using the appropriate symbol (from the Greek alphabet), designate the partial charge on each atom in the pair when they are sharing electrons in a covalent bond. Pair of Atoms H-Br F-N O-C Cl-F Direction in which electrons Partial charges are pulled H-Br H-Br Name: _______________________________________________ Question II. Use the guide handed out in class to write the electron dot structures of the following molecules. Please show your work below. Place each of your electron dot structures in the appropriate box on the next page. For each molecule, circle the electron pairs in your dot structure that would be considered the ‘lone pair(s)”.
