Answer:
This structure is correct due to the total number of bonds and electrons.
Explanation:
We know that all atoms in a compound are expected to obey the octet rule and we use this rule to ascertain the correctness of any chemical structure.
The structure of carbon IV oxide drawn perfectly satisfies the octet rule for each atom. Each atom in the molecule has eight electrons around its valence shell.
Therefore,since CO2 has sixteen valence electrons, we can conclude that; this structure is correct due to the total number of bonds and electrons.
