(a)
Interpretation:
The chirality center in ketoprofenmolecule should be determined.
Concept Introduction:
Organic compounds are the compounds that are mainly composed of C and H atoms. The branch of chemistry that deals with the preparation, reactions and properties of organic compounds called
Constitutional isomers can be defined as the pair of molecules with same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula, but they have different arrangements of atoms in the three-dimensional space.
(b)
Interpretation:
The chirality center in the methylphenidate molecule should be determined.
Concept Introduction:
Organic compounds are the compounds that are mainly composed of C and H atoms. The branch of chemistry that deals with the preparation, reactions and properties of organic compounds called organic chemistry. The molecular formula of an organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with chemical bonds and the arrangement of atoms in the molecule. The compounds with same molecular formula and different structural formula are called isomers. Isomers can be classified as constitutional isomers and stereoisomers.
Constitutional isomers can be defined as the pair of molecules with same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula, but they have different arrangements of atoms in the three-dimensional space.
