Question

In a carbon dioxide molecule (O=C=O), which statement is true of the electrons?

A) The electrons are being shared between the carbon and oxygen atoms.
B) The carbon has gained electrons, giving it a negative charge.
C) The electrons are involved in ionic bonding.
D) The oxygens have gained electrons, giving them a negative charge.

Answer 1

Answer: Option A.

The electrons are being shared between the carbon and oxygen atoms.

Explanation:The electrons are being shared between the carbon and oxygen atoms because each oxygen share four electrons with the central carbon, therefore carbon atoms have 8 electrons that is shared with oxygen. The oxygen have two shared pairs in double bond and two lone pairs in non bonding. Carbon and oxygen form covalent bond. This satisfies the octet rule because the electrons are shared in both oxygen and carbon octet.
