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...

EXPERIMENT W12: ORGANIC STRUCTURES AND MOLECULAR MODELS 7. 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. What hybrid orbital is used by...

3. Molecular Shapes Take a molecular model kit from the cart. Please read the cover of the kit and know what color represents which element. Black is used for carbon, while for hydrogen, green for chlorine, Also identify the bonds Short-grey used for single bonds. Long-grey used for multiple bonds.

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...
