Question

Question: Draw all possible stereoisomers of hepta-2,4-diene and label each double bond as E or Z.

Short answer

Answer

Step-by-step solution

E, Z isomers

A method is employed to name alkene like stereoisomers based on the positions of the functional group along with the double bond.

When the higher priority groups are on the same side across the double bond, the isomer is named as Z-isomer and when they face different side, the isomer is named E-isomer.

Examples are shown below:

Stereoisomers of hepta-2,4-diene

The different stereoisomers of the compound are given below:

(2Z,4Z)-hepta-2,4-diene

(2E,4E)-hepta-2,4-diene

(2E,4Z)-hepta-2,4-diene

(2Z,4E)-hepta-2,4-diene
