(a) Explain why ? bond resonance structures are ignored whenthere are ? bonds
and nonbonding electrons in a molecule. (b) Use curved arrownotation to draw all
reasonable resonance structures for the structures shown below.(c) Indicate and
explain which structure is the principal structure andrank/explain the contributions of
the minor structures. (d) Briefly explain what the minorresonance structure indicates
about the molecule.
2. (a) For the followingresonance hybrid structures draw the contributingresonance
structures. (b) Explain what is useful about drawing eachresonance hybrid structure. (c)
Explain what is not useful about drawing each resonance hybridstructure.
3. Explain why the structuresbelow do not have ? resonance structures or have
incorrect curved arrow notation.
