Concept explainers
Interpretation:
The chiral center and enantiomers of methamphetamine molecules 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 preparation, reactions, and properties of organic compounds is said to be the
Constitutional isomers can be defined as the pair of molecules with the same molecular formula but different structural formula. Stereoisomers have same molecular and structural formula but have different arrangement of atoms in the three-dimensional space.
Optical isomers are type of stereoisomers which have same molecular and structural formula but have different arrangement of atoms in the three-dimensional space. The essential condition for a molecule to be optical isomer is the presence of chiral carbon atom.

- Label the chirality center (if one exists) in each compound. A compound may contain zero or one chirality center.arrow_forwardCoibacin B is a natural product that exhibits potent anti-inflammatory activity and potential activity in the treatment of leishmaniasis, a disease caused by certain parasites. Assign the configuration of each chiral center in coibacin B H.arrow_forwardSimvastatin (trade name: ZocorTM) is a pharmaceutical used to treat elevated blood lipids (i.e. high cholesterol). It contains 7 chirality centers (which allows for 128 different stereoisomers!) Determine the configuration of each chirality center. H H HO H H H H H H H H H O H Harrow_forward
- Is the following compound chiral, and does it have an enantiomer? Me -Me It is chiral, and it has an enantiomer. It is chiral, but it does not have an enantiomer. It is not chiral, and it does not have an enantiomer. It is not chiral, but it does have an enantiomer.arrow_forwardA) ОН B) HO. Molecule A is achiral and molecule B is chiral Molecule A is chiral and molecule B is achiral Both molecules are achiral. Both molecules are chiral.arrow_forwardAlthough fresh human sweat has no odor, enzymes in skin bacteria form a variety of compounds with distinctive, pungent odors. The two enantiomers of 3-methyl-3-sulfanyl-1-hexanol (A), which smell somewhat differently, contribute to the characteristic foul odor of sweat.

- One of the analgesics has a chiral center. Which compound is it? One of the two enantiomers is far more effective at reducing pain than the other.arrow_forward8. Two structures of Lipitor (a drug used to lower cholesterol) are shown below. (a) Determine the absolute configuration of each indicated stereocenter. Fill in the correct circle. (b) Determine if the two structures are the same compound or stereoisomers. Fill in the correct circle. (a) НО. Carbon a HO O OH Carbon a: OR OS Carbon b H N Carbon b: R OS of H Carbon c: OR OS OH OH Carbon c F Carbon d: R OS OH Carbon d (b) The two structures are: O the same compound O stereoisomersarrow_forwardDiastereomers are a type of a stereoisomer. Diastereomerism occurs when two or more stereoisomers of a compound have different configurations at one or more (but not all) of the equivalent (related) stereocenters and are not mirror images of each other.
