Select all of the highlighted atoms that are likely to have a negative charge in at least one of the resonance structures of B. 10 11 1 8 12 2 3 N4 765 13 EC- N

Which of the highlighted chemical bonds in the molecules below is longest? Shortest? In between? Which highlighted bond requires the highest energy to break? Lowest? In between? Answer these questions by completing the second and third columns in the table.

Please guide me on how to draw the best resonance structure, thank you.

Each blank only has one correct answer: Answer choices for blank 1:  A B C D Answer choices for blank 2:  it has fewer charges   the formal charges follow elecronegativity the best   it is the onlu one that does not violte the octate rule

is this correct?

Consider the resonance structures of formate. Y-Y Select the true statements about the resonance structures. I The actual structure of formate is an average of the two resonance forms. Each oxygen atom has a double bond 50% of the time. O Each carbon-oxygen bond is somewhere between a single and double bond. The actual structure of formate switches back and forth between the two resonance forms. 0OO0
