We’re being asked to determine the preferred structure for carbon dioxide (CO2).
For this problem, we need to compare the formal charge of each structure.
Recall that the formula for the formal charge is:
These two electron-dot formulas for carbon dioxide (given below) both satisfy the octet rule, but one is preferred over the other. Which of the statements identifies the preferred structure and also the reason it is preferred?
a) Structure 1 is preferred because the triple bond is stronger than the double bond.
b) Structure 1 is preferred because the formal charge on carbon is negative.
c) Structure 2 is preferred because the formal charge on each atom is zero.
d) Structure 2 is preferred because the bonds are equal.
