Draw three resonance structures for CO2. This species has its three atoms bonded sequentially in the following fashion: O-C-O. Draw your resonance structures so that the atoms in them are bonded together in this order. Select the most important resonance structure for this species based on the formal charges on the atoms of the three resonance structures you have drawn. Now select the statement from the multiple choices which is true about this most important resonance structure.

In the most important resonance structure of CO2 :

a) The leftmost bond (between O and C) is a single bond.

b) The rightmost bond (between C and O) is a triple bond.

c) The formal charge on the leftmost (O) atom is -1.

d) The number of nonbonding pairs (lone pairs) of electrons on the leftmost (O) atom is 4.

e) The number of nonbonding (lone) pairs of electrons on the rightmost (O) atom is 2.
