differences in Electronegativity: greater than 1.7, 0.5 to 1.7, less than 0.5, = to 0.5
Bond type: ionic, polar covalent, covalent, nonpolar covalent
Which statement below correctly describes the bond between carbon and oxygen in a compound?
Use the charts above to help you answer the question.
(Hint: Determine the electronegativity difference between the 2 elements, then use the difference to determine the type of compound. )
a
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with oxygen pulling the electrons toward it.
b
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with carbon pulling the electrons toward it.
c
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is nonpolar covalent.
d
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is ionic.
b
Carbon and oxygen have an electronegativity difference of 1.0, so the bond is polar covalent, with carbon pulling the electrons toward it.
