Question

1. Molecular set #2:
   • Construct a model of ethane, C₂H₆.
     • Draw it in 3D.
     • State the general shape and geometry of the molecule at each carbon atom.
     • State if there free rotation around the C-C bond or not.
     • State if it's possible to have constitutional isomers of ethane or not.
   • Now replace two of the hydrogens with chlorines.
     • Draw it in 3D.
     • Name and draw all of possible isomers .
     • Name your isomers.

3. Molecular set #3:

   • Construct a model of the compound n-butane (CH₃CH₂CH₂CH₃).
     • Draw two 3D models:
     • One with the most crowding.
     • One with the least crowding
     • Which of these two conformations of butane would be most stable and why?
     • Construct a constitutional isomer of n-butane.
     • Name this compound.
