Question

1. Complete Data Table 2 using the Periodic Table of Electronegativities and the Bonding Scale to determine the type of bond that each set of atoms would exhibit if they formed a bond. For polar covalent bonds only, draw a vector between atoms showing bond polarity in the last column 2. Determine the electronegativity difference and bond polarity for each bond in compounds in Data Table 1. Record your calculations and bond polarity determination under Activity 4 in Data Table 1 3. Add appropriate bond polarity vectors beside each bond in the perspective drawings under Activity 3 in Data Table 1 4. Determine whether each molecule exhibits a dipole moment and write "yes" or "no" in the space provided under Activity 4 in Data Table 1. If the drawing is not clear, remake the model of the molecule to help visualize the shape and direction of the charges 5. Determine whether each molecule is polar and write "polar" or "nonpolar" in the space provided under Activity 4 in Data Table 1
