Which bond in each pair is more polar? Select the single best answer for each part.
Note: Reference the Periodic Table for the electronegativity values. Si-Br Si-C1,
The electronegativity values for Si, Br, and Cl are as follows:
Si: 1.90
Br: 2.96
Cl: 3.16
Based on these values:
1) Si-Br: The electronegativity difference is 2.96 - 1.90 = 1.06
2) Si-Cl: The electronegativity difference is 3.16 - 1.90 = 1.26
Therefore, the Si-Cl bond is more polar than the Si-Br bond.
