Build models of all possible isomers of CHCl, and then draw and name the Lewis Structure for each Isomers that differ in their relative geometry (or orientation) across a rigid double bond are called geometrie isomers. Circle your geometric isomers. Label each molecule as polar or non-polar. Certain physical properties of molecules, such as boiling point, are dependent on the degree of polanty of a molecule.

Date Laboratory Exercises Using a molecular modeling kit, construct models of each of the compounds in the tables below. Complete the following three tables by first drawing a simple sketch of the molecule showing which atoms are attached to each other, the number of bonds between each pair of atoms, and any nonbonding electrons. Then, draw the molecule again showing the actual shape and the angles between the atoms as accurately as you can. The first one has been completed...

Make a model of each of the chair conformations of cis-1,2-dibromocyclo- hexane, and show that they are nonsuperimpoasble mirror images of each other. Is cis-1,2-dibromocyclohexane isomer optically active? The planar structure has a plane of symmetry, but the chair conformation doesn't! Yes _No Although each conformer is chiral, the rapid interconversion between the two at room temperature means they cannot be separated. The compound is not chiral. Identifying chirality in cyclohexane derivatives can seem daunting. Fortunately we can greatly simplify...
