Z- based on the Cahn-Ingold-Prelog priority rules (review) Stability: There are 3 factors that influence alkene stability: 1. Degree of substitution: more highly alkylated alkenes are more stable‚ so tetra > tri > di > mono-substituted. 2. Stereochemistry: trans > cis due to reduced steric interactions when R groups are on opposite sides of the double bond. 3. Conjugated alkenes are more stable than isolated alkenes. |[pic] |[pic] |more stable than |[pic] |[pic] | |trans-2-butene
