Concept explainers
(a)
Interpretation:
In the given molecule, the atoms that are required to be in the same plane are to be circled.
Concept introduction:
Groups that are connected by a single bond have the ability to rotate freely relative to each other. But the groups which are connected by a double bond do not rotate freely. In the case of a double bond, the pi bond would be broken because during rotation, the overlap between the p orbitals would be destroyed. When two atoms are connected by a double bond, those two atoms and all the atoms directly attached to them, prefer to lie in the same plane.
(b)

In the given molecule, the atoms that are required to be in the same plane are to be circled.
