(a)
Interpretation:
The synthesis of fexofenadin has to be shown.
Concept introduction:
The Grignard reaction:
Alkyl, vinyl, or aryl-magnesium halides (
(b)
Interpretation:
The possible stereoisomer’s has to be shown if the product is chiral.
Concept introduction:
Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.
Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.
Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.
Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.
Achiral:
A molecule is superimposable on its mirror image is called achiral molecule.
