To determine the nature of the bonds in carbon dioxide (CO2), we first need to know the electronegativities of carbon and oxygen.
- The electronegativity of carbon (C) is approximately 2.5.
- The electronegativity of oxygen (O) is approximately 3.5.
Now, let's calculate the electronegativity difference:
- Electronegativity difference = |Electronegativity of O - Electronegativity of C| = |3.5 - 2.5| = 1.0.
In terms of bond classification based on electronegativity differences:
- A difference of 0.0 to 0.4 typically indicates a nonpolar covalent bond.
- A difference of 0.5 to 1.6 indicates a polar covalent bond.
- A difference greater than 1.6 usually indicates an ionic bond.
Since the electronegativity difference between carbon and oxygen is 1.0, the bond is classified as polar covalent, with oxygen being more electronegative and pulling the electrons toward itself.
Thus, the correct statement is:
**Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with oxygen pulling the electrons toward it.**
- The electronegativity of carbon (C) is approximately 2.5.
- The electronegativity of oxygen (O) is approximately 3.5.
Now, let's calculate the electronegativity difference:
- Electronegativity difference = |Electronegativity of O - Electronegativity of C| = |3.5 - 2.5| = 1.0.
In terms of bond classification based on electronegativity differences:
- A difference of 0.0 to 0.4 typically indicates a nonpolar covalent bond.
- A difference of 0.5 to 1.6 indicates a polar covalent bond.
- A difference greater than 1.6 usually indicates an ionic bond.
Since the electronegativity difference between carbon and oxygen is 1.0, the bond is classified as polar covalent, with oxygen being more electronegative and pulling the electrons toward itself.
Thus, the correct statement is:
**Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with oxygen pulling the electrons toward it.**
