Determining Nonpolar Molecules Answers and Explanation:

Sure, I can help you with that. The image you sent shows five Lewis structures with the following chemical formulas:

• E) All of the above are nonpolar and contain a polar covalent bond.

The question asks you to choose the compound that contains at least one polar covalent bond but is a nonpolar molecule overall.

Here's a more detailed explanation of each molecule:

• A) GeH2Br2: This molecule has two Ge-H bonds and two Ge-Br bonds. Ge is less electronegative than both H and Br. Therefore, the Ge-H bonds are polar (H is more electronegative than Ge) and the Ge-Br bonds are also polar (Br is more electronegative than Ge). However, the molecule has a bent V-shape geometry. The polarities of the two Ge-H bonds and the two Ge-Br bonds partially cancel each other out due to the geometry, making GeH2Br2 a nonpolar molecule.
