Interpretation:
The line-and-wedge formula of
Concept introduction:
The naming of the chiral center and geometric isomers are based on Cahn-Ingold-Prelog priority rules. If the priority assigned to each group attached to the chiral center in a molecule is in a clockwise direction, then it is the R-stereoisomer, and if this is counter-clockwise, then it is the S-stereoisomer. R and S-stereoisomer are mirror images of each other.
(b)
Interpretation:
The specific rotation of pure
Concept introduction:
A carbon atom that has four nonequivalent atoms or groups attached to it is known as the chiral carbon atom. Chiral carbon centers are also called as asymmetric or stereogenic centers. A chiral molecule is an optically active molecule. It rotates the plane of a plane polarized light. The enantiomeric excess of a sample is given as,
(c)
Interpretation:
The percentage of each enantiomer present in the given sample is to be calculated.
