Concept explainers
(a)
Interpretation: The given compound is to be labeled as cis or trans and then the second chair conformation is to be drawn.
Concept introduction: A cis isomer contains two substituents/groups on the same side, either both on down bonds or both on up bonds. On the other hand, a trans isomer contains two substituents/groups on the opposite sides, one down and one up.
(b)
Interpretation: The given compound is to be labeled as cis or trans and then the second chair conformation is to be drawn.
Concept introduction: A cis isomer contains two substituents/groups on the same side, either both on down bonds or both on up bonds. On the other hand, a trans isomer contains two substituents/groups on the opposite sides, one down and one up.
