(a)
Interpretation: The structure and name of all the stereoisomers of 2,3-dichloropentane and 2,3-dichlorobutane needs to be determined.Also, the missing isomerof 2,3-dichlorobutane from the mentioned problem needs to be determined.
Concept Introduction:Number of stereoisomers (N) of a compound depends on the number of chiral centers. The formula is as follows:
Here, n is number of chiral carbon atoms in the molecule.
IUPAC nomenclatureis the method that is used to name the organic compounds in which the rules are governed by the International Union of Pure and Applied Chemistry.
Rules:
- Identify the parent chain from the given name of the compound that is written at the last.
- Find the position of the halogens present in the parent chain and attach those substituents in the corresponding position.
(b)
Interpretation: This is to be explained that how the number of stereoisomers of 2,3-dichloropentane is 4, but that of 2,3-dichlorobutane is 3.
Concept Introduction:If the different arrangement of atoms in a compound results in same formation of compound of same name thus, they are not condidered as stereiosiomers.
