Answer
The given resonance structure is not very important to the overall structure of carbon dioxide. This is because here the formal charge is +1 on oxygen, which is a highly electronegative element.
Work Step by Step
We know,
formal charge = no. of valence electrons - (no. of nonbonding electrons + 1/2 no. of shared electrons)
For oxygen, (triple bonded to carbon)
Formal charge = 6 - (2+ 1/2*6) = 1
The formal charge is +1 on oxygen, which is a highly electronegative element. So, the structure is not very stable and is not very important to the overall structure of carbon dioxide.
