Among the following, the compound having conjugated double bonds is
- hepta-1,6-diene
- hepta-1,3-diene
- hepta-1,4-diene
- hepta-1,5-diene
Answer
(2) hepta-1,3-diene
Solution
In hepta-1,3-diene (CH2=CH-CH=CH-CH2-CH2-CH3), the two double bonds are separated by a single bond, forming a conjugated system (alternating double and single bonds).
