Give the number of lone pairs around the central atom and the molecular geometry of SeF₄. A) 0 lone pairs, tetrahedral B) 1 lone pair, distorted tetrahedron (seesaw) C) 1 lone pair, square pyramidal D) 1 lone pair, tetrahedral E) 2 lone pairs, square planar

Question

Quizplus · Accepted Answer

The central atom in SeF₄ is Se which has 4 electron pairs around it, including one lone pair. This gives it a distorted tetrahedral geometry or a "seesaw" shape. Therefore, choice B is the only option that fits both criteria.
