Interpretation:
The structure for each of the given name is to be drawn.
Concept introduction:
In case of rings containing seven or less than seven carbon atoms, the Z/E configuration is usually omitted for double bonds which are a part of the ring. The E configuration about the double bond is not stable due to ring strain. It is understood that the double bonded carbon atoms have a configuration such that they are cis to each other. In case of rings consisting of more than seven carbon atoms, the double bond, which is a part of the ring, can have E or Z configuration.
If the higher priority groups, attached to the double bonded carbon atoms, are on the same side of the double bond, the

If the higher priority groups, attached to the double bonded carbon atoms, are on the same side of the double bond, the alkene is assigned Z configuration. If the higher priority groups, attached to the double bonded carbon atoms, are on the opposite side of the double bond, the alkene is assigned E configuration.
