present two Cl atoms (cis-geometry.) Make a second model of ethene and replace H2 and H3 with two Cl's (trans-geometry.)Are the cis-and trans-models the same?If you replaced H1 and H4 with Cl's, would it be the cis-, the trans- or another geometry?If you replaced H2 and H4 what is the geometry?If you replaced H1 and H2 what is the geometry?Draw planar structural diagrams for each of the following molecules. Your drawing should show correct bond angles.H2C=CH2H2C=CHClcis-HCIC=CClH trans-HCIC-CClH C12C=CH2 Linear (sp hybridization)BeH2. Use the center with 6 prongs for the Be atom and put two rods of the same color opposite each other then make a model of beryllium dihydride.GeometryLewis dot diagram# of s bonds on Be_________# of non bonding pairs on Be__________# atoms in one planeApproximate H-Be-H angleH - C = C - HUse two of the 6 prong centers for the carbon atoms and two same color rods for the H's to make a model of ethyne. This is a linear molecule.GeometryLewis dot diagram# of s bonds on C____________# of p bonds on C____________# atoms in one plane____________Approximate H-C-C angle________If bond axis is x, what are along y and z? ______________Is there a free rotation along C-C bond? Why?Octahedral (sp3d2 hybridization)SF6 Use the 6 prong center for the S atom and rods of the same color for the 6 F's to make a model of sulfur hexafluoride.GeometryLewis dot diagram# of s bonds on S# of p bonds on S# of lone pairs on SApproximate F-S-F angleBrF5Remove one of the rods from the SF6 model to make a model for bromine pentafluoride.GeometryLewis dot diagram# of s bonds on Br# of p bonds on Br# of lone pairs on BrApproximate F-Br-F angleXeF4. Use a 6 prong center for the Xe and rods of the same color for the 4 F's. Place all the F's in the same plane around the Xe to make a model of xenon tetrafluoride.GeometryLewis dot diagram# of s bonds on Xe# of p bonds on Xe# of lone pairs on XeApproximate F-Xe-F angleLone pair to lone pair an...
