Question: For each molecule, draw its shape using Lewis structures and VSEPR theory. Include your steps in creating each sketch. Each diagram should include labelled electronegativities and partial charges for each atom within the molecule, and vector arrows representing the magnitude and direction of each bond dipole and net dipole (for polar molecules). Finally, determine whether the molecule is polar or non-polar and explain your rationale based on bond polarity and molecular shape. CH2Cl2 NI3 CH2O BeF2 SF6 SO2 HBr
