Step 1:I'll solve this problem step by step, focusing on electronegativity to determine the negative pole in the BrI molecule.
Step 2:: Identify the Electronegativity of Bromine and Iodine
- Bromine (Br) electronegativity: $$2.96
- Iodine (I) electronegativity: 2.66
Step 3:: Calculate the Electronegativity Difference
- Electronegativity difference = $$|2.96 - 2.66| = 0.30
Step 4:: Analyze the Electronegativity Trend
- Bromine is more electronegative than Iodine - This means electrons will be more attracted to the Bromine atom
Step 5:: Determine Polarity
- The more electronegative atom (Bromine) will have a partial negative charge - The less electronegative atom (Iodine) will have a partial positive charge
Final Answer
In the BrI molecule, Bromine (Br) is the negative pole due to its higher electronegativity.
