Step 1:I'll solve this step by step, focusing on bond polarity determination.
Step 2:: Understanding Bond Polarity
Bond polarity depends on the electronegativity difference between two atoms. The greater the electronegativity difference, the more polar the bond.
Step 3:: Recall Electronegativity Values
Let's review the Pauling electronegativity values for these elements: - S: 2.58 - F: 3.98 - I: 2.66 - Cl: 3.16 - Te: 2.1 - B: 2.04 - N: 3.04
Step 4:: Calculate Electronegativity Differences
B and N: $$|3.04 - 2.04| = 1.00
A. B. C. D.
Step 5:: Determine Most Polar Bond
The largest electronegativity difference indicates the most polar bond. Comparing the differences, Te and F has the largest difference of 1.88.
Final Answer
Te and F forms the most polar bond.
