B. Identify what kind of Bond is present in the following molecules. (You may show your solution 1. CH4 1. CO2 1. C2H2

Formulas of ionic compounds

Draw the lewis structure for SO42- . Then identify the electron pair geometry (EPG), molecular geometry (MG) bond angle (BA), and polarity (P). Select one: a. EPG: tetrahedral, MG: tetrahedral, BA: 120*, P: non-polar b. EPG: tetrahedral, MG: tetrahedral, BA: 109.5*, P: non-polar c. EPG: tetrahedral, MG: bent, BA: 109.5*, P: polar d. EPG: trigonal planar, MG: tetrahedral, BA: 109.5*, P: non-polar

Consider the molecules — BrF5. A. Draw the best Lewis structure for this molecule. Label any atoms with nonzero formal charge. B. Label each bond angle. As part of your answer be sure to include if it is more or less than the ideal bond angle.  C. What is the electron geometry around the bromine atom? D. Are the bonds in the molecule polar? E. Is the overall molecule polar? — CH2 F2 . A. Draw the best Lewis structure for this molecule. B. Label each bond angle. Answers for A-D here: C. Redraw the shape of the molecule. Draw all dipoles. D. Is the overall molecule polar? — Consider the molecule CH2 CF2 . A. Draw the best Lewis structure for this molecule. B. Label each bond angle. C.
