(a)
Interpretation:
The synthesis of carbinoxamine has to be shown.
Concept introduction:
The Grignard reaction:
Alkyl, vinyl, or aryl-magnesium halides (
Grignard reagent is reaction with carbonyl compound such as
(b)
Interpretation:
The chirality of Carbinoxamine is to be identified and the possible stereoisomers has to be identified in the given synthesis.
Concept introduction:
Chiral:
A molecule is non superimposable on its mirror image is called chiral molecule.
Four different atoms attached to a carbon atom is called chiral molecule.
Isomer:
A molecule having the same molecular formula but with different chemical structure is called isomer.
Stereoisomers:
Stereoisomers are molecules that have the same molecular formula and they differ only in arrangement of atom in three-dimensional space.
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.
