Concept explainers
(a)
Interpretation: The relation between the given pair of compounds is to be stated.
Concept introduction: Constitutional isomers have same molecular formula but differ in spatial arrangements of substituents. Identical isomers have same molecular formula as well as same spatial arrangements of substituents. The stereoisomers have same chemical formula but differ only in the spatial arrangement of their atoms.
(b)
Interpretation: The given compounds are to be labeled as cis or trans isomer.
Concept introduction: Cis–trans isomers are geometrical isomers. Cis-isomer contains two groups on the same side of the ring. Trans-isomer contains two groups on the opposite side of the ring.
(c)
Interpretation: The wedge-dash of
Concept introduction: Cis–trans isomers are geometrical isomers. Cis-isomer contains two groups on the same side of the ring. Trans-isomer contains two groups on the opposite side of the ring.
(d)
Interpretation: The wedge-dash of
Concept introduction: Cis–trans isomers are geometrical isomers. Cis-isomer contains two groups on the same side of the ring. Trans-isomer contains two groups on the opposite side of the ring.
