a.
To determine:
The structure of both the cis and trans stereoisomers for the given compound using wedge-and-dash bonds.
Concept introduction:
Cis-trans isomers come under the geometric isomerism and are a form of stereoisomerism. The prefix “cis” means “on the same side” and the prefix “trans” means “on opposite sides”.
When the heteroatom is cis then one heteroatom is at axial position and the other one is at equatorial position. When the heteroatom is trans, then both substituents are at equatorial position but are on the opposite sides of the ring with respect to each other.
The Trans isomers have high symmetry and are more stable than cis isomers.
