Draw all the geometrical isomers of 2,4-hexadiene and label each by the cis/trans and the E/Z system.

Answer:
3.00
Solution:

2,4-Hexadiene, CH₃CH=CH-CH=CHCH₃, is symmetrical : the cis,trans and trans,cis forms are identical, so only 3 geometrical isomers exist :

cis,cis-2,4-Hexadiene or (Z,Z)-2,4-Hexadiene :

structure

cis,trans-2,4-Hexadiene or (Z,E)-2,4-Hexadiene :

structure

trans,trans-2,4-Hexadiene or (E,E)-2,4-Hexadiene :

structure
