Boron’s valence shell fills 2 electrons in the s-orbital and a single electron in the p-orbital to form 3 covalent bonds with bromide and no paired electrons left over, so the bromide atoms spread as far away from each other as possible, to the points of a triangle with the boron in the center. Thus, the ion will be . Concept: Some molecular shapes are seen as perfect and will always lead to a non-polar molecule overall.

Find answers to questions asked by student like you, Draw the Lewis structure of PBr3 and then determine if the molecule is polar or nonpolar. Each of the bonds is polar, but the molecule as a whole is nonpolar. The process you performed in this lab is known as extraction—for example, one compound moves into the nonpolar solvent layer, the other stays in the polar solvent layer. a. a.
