6. Answer the following questions that relate to chemical bonding. (a) Two Lewis structures can be drawn for the OPF3 molecule, as shown below. :Ö: :F-P-F: :F-P-F: :F: :F: Structure 1 Structure 2 (i) (ii) How many sigma and how many pi bonds are in Structure 1? 4 and 1 σ Does Structure 1 demonstrate resonance? Justify your decision. No it does not demonstrate resonance because the double bond is w/ the there oxygen mic and disn't another oxygen mild to transfer the bond to. (iii) Which one of the two structures best represents a molecule of OPF3? Justify your answer in terms of formal charge.
