Concept explainers
(a)
To calculate: The number of chiral centers that are present in isoleucine.
Introduction:
In carbon atoms, the chiral centers are those that contain four different or non-identical functional groups. Chiral centers are also referred as stereogenic centers. The molecules with at least one chiral center are referred as chiral molecules.
(b)
To calculate: The number of optical isomers present in isoleucine.
Introduction:
Isomers are the compounds that have similar molecular formula, but different structural formula. L-form (levo-rotatory) and D-form (dextro-rotatory) are optical isomers or stereoisomers. They have the same chemical structure, but their spatial arrangement is different.
(c)
To draw: The perspective formulae for all the optical isomers of isoleucine.
Introduction:
Isomers are the compounds that have similar molecular formula, but different structural formula. L-form (levo rotatory) and D-form (dextro rotatory) are optical isomers or stereoisomers.
