19. Does the name 2-butene indicate which of the stereoisomers above is being referred to? 20. To indicate the difference between alkenes that have 2 substituents across a double bond, use the prefix trans (across the double bond relative to each other) or cis (same side of the double bond t each other). Thus, the correct IUPAC names for the compounds above are cis-2-butene and trans butene. 21. Add cis or trans where needed to the IUPAC names in the alkene CTQ question above.
