For this problem, we need to do the following steps:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Draw dipole arrows for each bond.
Step 5: Determine the polarity of the molecule.
Step 1: Br is the central atom.
Step 2: The total number of valence electrons present in BrI5 is:
Group Valence Electrons
Br 7A 1 × 7 e– = 7 e–
l 7A 5 × 7 e– = 35 e–
Total: 42 valence e–
Which choice best describes the polarity of BrI5?
a. The molecule is polar and has polar bonds.
b. The molecule is nonpolar and has polar bonds.
c. The molecule is polar and has nonpolar bonds.
d. The molecule is nonpolar and has nonpolar bonds.
