Concept explainers
A.
To determine: A model for the given compounds, the most symmetric conformation for them and if they are capable of showing optical activity.
Interpretation: A model for the given compounds is to be made, the most symmetric conformation for them is to be drawn and their ability to show optical activity is to be predicted.
Concept introduction: A chiral carbon atom is attached to four different atoms or group of atoms and shows a tetrahedral geometry. The mirror image of a chiral compound is non-super imposable. The two different forms in which a single chiral carbon can exist are referred to as enantiomers. The number of enantiomers of a molecule depends on the number of chiral centers.
B.
To determine: Each asymmetric carbon atom in part (1) marked by star and labeled as (R) or (S) and comparison of the results with predictions about the asymmetric carbons.
Interpretation: Each asymmetric carbon atom in part (1) is to be marked by star and labeled as (R) or (S) and comparison of the results with predictions about the asymmetric carbons is to be done.
