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 Objectives.

The atoms or groups of atoms attached to the carbon atoms on the double bond may form two different structures, which are called . Purpose. : Allows you to communicate precisely what you want to say.. A writer uses definition to:. Let the reader know what you mean when you use unfamiliar words (ex: accoutrement), words that are open to interpretation (ex: freedom), or familiar words that are used in a particular sense. . Two molecules are isomers of each other if they have the same molecular formula, but they are different in some way.. Their atoms can be connected in different ways; they can differ as a result of rotations about single bonds; or they can be mirror images of each other.. that optical isomerism is a result of chirality in molecules with a . single chiral . centre. understand . that optical isomerism results from chiral centre(s) in . a molecule with . asymmetric carbon atom(s) and that optical isomers are object .
