Concept explainers
a)
Interpretation:
The number of stereoisomers that are possible for ketoheptose is to be stated.
Concept Introduction:
Stereoisomers are the isomers having same structural formula but they differ in the arrangement of atoms in space.
Enantiomer:
An enantiomer also known as an optical isomer is one of two stereoisomers that are mirror images of each other that are non-supposable.
The number of possible stereoisomers is calculated as
b)
Interpretation:
The number of stereoisomers that are possible for aldoheptose is to be stated.
Concept Introduction:
Stereoisomers are the isomers having same structural formula but they differ in the arrangement of atoms in space.
Enantiomer:
An enantiomer also known as an optical isomer is one of two stereoisomers that are mirror images of each other that are non-supposable.
The number of possible stereoisomers is calculated as
c)
Interpretation:
The number of stereoisomers that are possible for a ketotriose is to be stated.
