4-Bromobut-1-ene is the name of which among the following alkenes?
Correct answer: D. CH2Br-CH2-CH=CH2
- A. CH2Br-CH2=CH-CH2
- B. CH2Br-CH2-CH-CH2
- C. CH2Br=CH2-CH=CH2
- D. CH2Br-CH2-CH=CH2
Explanation
4-Bromobut-1-ene indicates that the alkene is at the 1st position and the bromine is at the 4th position. The correct answer is Option D, where the alkene is correctly placed before the bromine according to nomenclature rules for hydrocarbons.
