Valence bond theory predicts that tin will use __________ hybrid orbitals in SnCl₃⁻. A)sp B)sp ² C)sp ³ D)sp ³ d E)sp ³ d ²

Question

Quizplus · Accepted Answer

The central tin atom in SnCl₃⁻ would contribute one valence electron, while each chlorine and sulfur atom would contribute seven and six valence electrons, respectively. The negative charge reduces the total count by one electron. To determine the hybridization of the tin atom, we can first look at the number of electron groups around the tin atom. The tin atom is bonded to four atoms, and there is also one lone pair on the tin. This gives a total of five electron groups around the tin atom. To accommodate these electron groups, the tin atom would need to hybridize its five valence orbitals. Thus, the hybridization of the tin atom can be predicted as sp ³.
