For geometric isomers around double bonds, the old cis/trans system fails when there are more than two different substituents. The system uses the same Cahn-Ingold-Prelog priority rules:
Place the lowest priority group (4) pointing away from the viewer. Subrata Sengupta Stereochemistry Pdf

: Detailed look at enantiomers and optical activity.
Dedicate study sessions entirely to converting one molecular projection into another. Mastery over these representations prevents trivial errors during exams.
These molecules have the same molecular formula but different bonding connectivity. For example, butane and isobutane share the formula but have entirely different carbon skeletons. Stereoisomers
