Explanation Sulfur is in the third row of the periodic table. So it has empty 3d orbitals, which S can use along with 3s and 3p orbitals to expand its octet. a) The Lewis structure of SF 6 is: There are six covalent bonds in the molecule. So the number of valence electrons around the central atom Sulfur is 12 instead of 8. Therefore S in SF 6 has expanded valence shell. b) The Lewis structure of SF 5 is: In this structure, central Sulfur atom forms five covalent bonds and is having one lone electron. So total number of valence electrons around Sulfur atom is 11 instead of 8. Therefore S in SF 5 has expanded valence shell. c) The molecule Lewis structure of SF 4 is:

You are trying to decide if there is a single reagent you can add that will make the following synthesis possible without any other major side products: xi 1. ☑ 2. H₂O хе i Draw the missing reagent X you think will make this synthesis work in the drawing area below. If there is no reagent that will make your desired product in good yield or without complications, just check the box under the drawing area and leave it blank. Click and drag to start drawing a structure. There is no reagent that will make this synthesis work without complications. : ☐ S ☐

Predict the major products of this organic reaction: H OH 1. LiAlH4 2. H₂O ? Note: be sure you use dash and wedge bonds when necessary, for example to distinguish between major products with different stereochemistry. Click and drag to start drawing a structure. G C टे

For each reaction below, decide if the first stable organic product that forms in solution will create a new C-C bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. NH2 CI MgCl ? Will the first product that forms in this reaction create a new CC bond? Yes No MgBr ? Will the first product that forms in this reaction create a new CC bond? Yes No G टे
