Question 1

• The more favorable resonance structures can be determined using formal charge.

Answer 1

• The more favorable resonance structures can be determined using formal charge.

Question 2

• A formal charge of zero is most stable; values of +1 or –1 are acceptable; any other value will not make a significant contribution to the resonance structure.

Answer 2

• A formal charge of zero is most stable; values of +1 or –1 are acceptable; any other value will not make a significant contribution to the resonance structure.

Question 3

• The connectivity of the atoms can be established by determining the configuration of atoms with the lowest formal charge.

Answer 3
