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.

Distinguish between normal and branched hydrocarbons. What is an alkane? What is a cyclic alkane? What are the two general formulas for alkanes? What is the hybridization of carbon atoms in alkanes? What are the bond angles in alkanes? Why are cyclopropane and cyclobutane so reactive? The normal (unbranched) hydrocarbons are often referred to as straight-chain hydrocarbons. What does this name refer to? Does it mean that the carbon atoms in a straight-chain hydrocarbon really have a linear arrangement? Explain. In the shorthand notation for cyclic alkanes, the hydrogens are usually omitted. How do you determine the number of hydrogens bonded to each carbon in a ring structure?arrow_forward
