Question

3. Draw resonance structures for the following molecules. favorable structure, if any Calculate formal charge for each atom. Circle the most a) сОвг» b) CH CONH2 (connectivity as shown below) Н. H Н 4. For each of the following, draw all bond dipoles on the first structure, then draw the net dipole on the second structure. If non-polar, write "no net" Bond :O: dipoles ex: : F Net O: dipole F F H+H ex: 5. The following are the two possible Lewis structures for CaH2 F. Will both of them have the same dipole moment? Draw bond dipoles, net dipole direction and explain your answer F H FH F H H F FICIE
