which of the following bonds is most polar? a f - f b o - f c o - i d o - cl
which of the following bonds is most polar? a f - f b o - f c o - i d o - cl
Answer
Brief Explanations:
The polarity of a bond depends on the electronegativity difference between the two atoms. The greater the electronegativity difference, the more polar the bond. Electronegativity values: F = 4.0, O = 3.5, Cl = 3.0, I = 2.5. Calculate the electronegativity differences for each option: A. F - F has an electronegativity difference of 0 (4.0 - 4.0). B. O - F: 4.0 - 3.5= 0.5. C. O - I: 3.5 - 2.5 = 1.0. D. O - Cl: 3.5 - 3.0 = 0.5. The O - I bond has the largest electronegativity difference among the options.
Answer:
C. O-I
