PDF-Stereochemistry Definition of Isomers

1 If two or more different compounds have the same molecular formula we call them isomers This is the general definition of isomer There are two major classes types of isomers and under these maj. Conformational isomers can be shown using Newman Projections or Sawhorses Newman Projections The circle in the Newman projection represents the carboncarbon bond viewed one carbon in front of the other Bonds attached to the front carbon are shown by 8 .
