For the below compounds, indicate whether the substituents are cis or trans, whether they are axial or equatorial, whether the conformation shown or the other chair conformation is more stable and whether the compound shown or one of its stereoisomers is more stable. WebJul 20, 2024 · An alkene group which can exist in two stereoisomeric forms is referred to as stereogenic. Alkene groups in natural unsaturated fatty acids are normally cis, but trans -fatty acids (which are thought to be associated with heart disease and other health problems) are found in some food products.
