(a)
Interpretation:
From the given Newman projection formulas of tartaric acid, same representations has to be identified.
Concept Introduction:
Priority rules:
- Priorities based on
atomic number
- When priority cannot be assigned on the basis of the atoms bonded directly to the chiral center
- Atoms participating in a double or triple bond are considered to be bonded to an equivalent number of phantom atoms.
For example,
- Priority assignment is made at the first point of difference between groups (should not be based on the larger group).
(b)
Interpretation:
From the given Newman projection formulas of tartaric acid, enantiomeric representations has to be identified.
Concept Introduction:
Enantiomers:
Stereoisomers having nonsuperposable mirror image relationship are called as enantiomers.
(c)
Interpretation:
From the given Newman projection formulas of tartaric acid, meso representation has to be identified.
Concept Introduction:
Meso compound:
It is an achiral compound having two or more chiral centers that also has chiral isomers.
(d)
Interpretation:
From the given Newman projection formulas of tartaric acid, diastereomers has to be identified.
Concept Introduction:
Diastereomers:
Stereoisomers that are not having nonsuperposable mirror image relationship are called as diastereomers.
