Concept explainers
(a)
Interpretation: The validation of the statement “Steroisomers always have the same molecular formula” has to be predicted.
Concept introduction: There are two types of isomers, constitutional isomers and stereoisomers. These are the broad classification of isomers that contains the same molecular formula. For stereoisomers, the difference lies in their arrangement in space whereas, for constitutional isomers the difference lies in the connectivity of atoms.
(b)
Interpretation: The validation of the statement “Steroisomers always have the same structural formula” has to be predicted.
Concept introduction: There are two types of isomers, constitutional isomers and stereoisomers. These are the broad classification of isomers that contains the same molecular formula. For stereoisomers, the difference lies in their arrangement in space whereas, for constitutional isomers the difference lies in the connectivity of atoms.
(c)
Interpretation: The validation of the statement “Steroisomers are always nonsuperimposable mirror imagaes of each other” has to be predicted.
Concept introduction: There are two types of stereoisomers, called enantiomers and diastereomers. The stereoisomers are those that do not form mirror images of each other are called diastereomers. The enantiomers are the molecules that form non-superimposable mirror images of each other.
(d)
Interpretation: The validation of the statement “Steroisomers always possess handedness” has to be predicted.
Concept introduction: Handedness is a form of isomerism. Those molecules that possess this property exist either in right-handed form or left-handed form. The isomers that possess the same structure and same molecular formula but, possess a small difference in the orientation of molecules in space are called stereoisomers.
