(a)
Interpretation:
For the given pairs of compounds, whether the compounds are in equilibrium at room temperature or they could be isolated from one another should be determined.
Concept introduction:
- 1,3-butadiene shows conformations due to free rotation of C2-C3 bond at room temperature. The conformations are s-cis and s-trans. The conformers are interconvertible or in equilibrium.
- E-Z designators are used as like cis-trans terminology for non-similar groups attached
alkenes. In E-Z designations, the groups attached to vinylic positions are checked by their priority on the basis of higher molecular weight. If the higher priority groups are on the same sides, then the configuration is designated as Z. If the higher priority groups are on the opposite sides, then the configuration is designated as E.
To identify: the given pairs of compounds, whether the compounds are in equilibrium at room temperature or they could be isolated from one another.
