Wkst 4.4: Bonding Worksheet 3. Identify the type of compound and depict the bonding with electron dot diagrams for each of the following (the “Periodic Table of Electronegativities” handout was used): SiTe2 Covalent compound! GeF4 Ionic compound! AsCl3 Covalent compound! each of these F should have 8 electrons NaI BaSe Covalent compound! Covalent compound! More feasible answers?!! These two questions included so that you are aware that strange (unexplainable?) thiings do exist. CCl4 Covalent compound! SrCl2 Ionic compound! Cl2 Covalent molecule! 4. Using the VSEPR technique, determine the shape of the following molecules: PBr5 SO3 BrI5 SF4+2 BH3 BeBr2 Central atom: P, 5 valence electrons 5 single bonds, 0 lone pair Total axes of symmetry: 5 Basic shape: trigonal bipyramid Actual shape: trigonal pyramid Bipyramid! Bond angles: 90° and 120° Non-polar molecule Central atom: S, 6 valence electrons One double, two coordinate bonds, 0 lone pair. Total axes of symmetry: 3 Basic shape: trigonal planar Actual shape: trigonal planar Bond angles: 120° Non-polar molecule Central atom: Br, 7 valence electrons 5 single bonds, 1 lone pair Total axes of symmetry: 6 Basic shape: octahedral Actual shape: square pyramid Bond angles: < 90° Polar molecule Central atom: S, 4 valence electrons 4 single bonds, 0 lone pairs Total axes of symmetry: 4 Basic shape: tetrahedral Actual shape: tetrahedral Bond angles: 109.5° Not a molecule! Central atom: B, 3 valence electrons 3 single bonds, no lone pairs Total axes of symmetry: 3 Basic shape: trigonal planar Actual shape: trigonal planar Bond angles: 120° Non-polar molecule Central atom: Be, 2 valence electrons 2 double bonds, no lone pairs Total axes of symmetry: 2 Basic shape: linear Actual shape: linear Bond angles: 180° Non-polar molecule CO3-2 IF3 BrCl4 - SeF2 RnCl2 SbH3 Central atom: C, 6 valence electrons 1 double and 2 coordinate bonds, no lone pairs Total axes of symmetry: 3 Basic shape: trigonal planar Actual shape: trigonal planar Bond angles: 120° Not a molecule! Central atom: I, 7 valence electrons 3 single bonds, 2 lone pairs Total axes of symmetry: 5 Basic shape: trigonal bipyramid Actual shape: T-shape Bond angles: <90° Polar molecule Central atom: Br, 8 valence electrons 4 single bonds, 2 lone pairs Total axes of symmetry: 6 Basic shape: octahedral Actual shape: square planar Bond angles: 90° Not a molecule! Central atom: Se, 6 valence electrons 2 single bonds, 2 lone pairs Total axes of symmetry: 4 Basic shape: tetrahedral Actual shape: V-shape Bond angles: << 109.5° Polar molecule Central atom: Rn, 8 valence electrons 2 single bonds, 3 lone pairs Total axes of symmetry: 5 Basic shape: trigonal bipyramid Actual shape: linear Bond angles: 180° Non-polar molecule Central atom: Sb, 5 valence electrons 3 single bonds, 1 lone pair Total axes of symmetry: 4 Basic shape: tetrahedral Actual shape: trigonal pyramid Bond angles: < 109.5° Polar molecule!
