Concept explainers
(a)
Interpretation:
The number of asymmetric carbon atoms that are present in an aldotetrose and structures of all the stereoisomers of aldotetrose are to be stated.
Concept introduction:
Carbon atom that is connected to four different types of groups or atoms is known as asymmetric or chiral carbon atom.
The compounds that have same molecular formula but they differ in the arrangement of atoms or groups in the space are known as stereoisomers.
(b)
Interpretation:
The number of asymmetric carbon atoms that are present in a ketotetrose and structures of all the stereoisomers of ketotetrose are to be stated.
Concept introduction:
Carbon atom that is connected to four different types of groups or atoms is known as asymmetric or chiral carbon atom.
The compounds that have same molecular formula but they differ in the arrangement of atoms or groups in the space are known as stereoisomers.
(c)
Interpretation:
The number of asymmetric carbon atoms and stereoisomers for an aldohexose and ketohexose is to be stated.
