Concept explainers
(a)
Interpretation:
To make model for compound A and draw the chair conformation, label as equatorial or axial and circle the most stable structure.
Concept Introduction:
Conformation is considered as the shape of molecule which it adopts when it rotates about its single or double bonds. When the molecule tries to take up the less strained position, it is the most stable form.
(b)
Interpretation:
To make model for compound B and consider the transannular and gauche interactions of its chair conformations and to elaborate the problems of conformation when compared to that of compound A.
Concept Introduction:
When a molecule tends to rotate about its single or double bonds, the molecule attains a specific shape based on its stability such that it has less strained position. This is said to be conformation.
When there is interaction between two non-bonding molecular groups in a large ring which are not adjacent, it is said to be trans annular. When the ring substitutes of the adjacent groups has a non- bonded interaction, it is said to be gauche interaction.
