To analyze the bonding in carbon dioxide (CO₂) and nitrite ion (NO₃⁻), let's first clarify that the question appears to refer to carbon and oxygen's electronegativity difference and its implications for the bond type.
-
Electronegativity of Carbon and Oxygen:
- Carbon has an electronegativity of about 2.5.
- Oxygen has an electronegativity of about 3.5.
-
Electronegativity Difference:
- The difference between the electronegativities of oxygen and carbon is 3.5 - 2.5 = 1.0.
-
Bond Character:
- Generally, a difference in electronegativity of 0 to 0.4 is considered nonpolar covalent, 0.5 to 1.7 is considered polar covalent, and a difference greater than 1.7 is generally classified as ionic. Given the difference of 1.0, the bond between carbon and oxygen is classified as polar covalent.
Given these details, the correct answer pertaining to the bond between carbon and oxygen in carbon dioxide and the nitrite ion (NO₃⁻) is:
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with oxygen pulling the electrons toward it.
