What is the name of CH3CH2CH=CHCH2CH=CHCH3 ?
- A
2,3-octadiene
- B
2,4-octadiene
- C
2,5-octadiene
- D
2,5-octadyne
The parent chain is 8 carbons long so it is -octa and diene because of the 2 double bonds. Also the position of these double bonds is correctly indicated in option C.
This option is incorrect.
2,3-octadiene: Incorrect because the double bonds are not located between carbons 2 and 3.
Incorrect
The compound has eight carbon atoms, so the base name is "octa-".
* It has two double bonds (=), so it's a "diene".
* The double bonds are located between carbons 2 and 3, and between carbons 4 and 5. Therefore, the correct name includes 2,4-
* Thus, the correct answer is 2,5-octadiene
