Concept explainers
(a)
Interpretation:
Cis-trans isomers for each compound are to be drawn.
Concept Introduction:
Stereoisomers: A compound has same molecular formula but differ in the spatial arrangement of atoms or groups in 3D-space.
Cis-isomer: In cis-configuration, the two identical substituents of the double bond are on the same side.
Trans-isomer: In trans-configuration, the two identical substituents of the double bond are on the opposite side and the term is included before the name as prefix.
