Question

3. Molecular set #4:

   • Construct the compound cyclopropane (C₃H₆).

     • Draw the 3D model.

     • State the shape of the molecule.

     • State the probable bond angles

     • Compare these angles to the normal bond angles for alkanes.

     • State a conclusion about possible strain in the molecule.

   • Now replace two hydrogens, one each on adjacent carbon atoms, with chlorines. This creates dichlorocyclopropane, C₃H₄Cl₂. Move one chlorine atom so that you have built both the cis and the trans isomers of this compound. These are called geometric isomers, and are a type of stereoisomers.

     • Draw the 3D structures of both.

     • Names the two compounds.

     • Construct another isomer that is not a stereoisomer, and draw it.

     • Name this other isomer.
