What reagents (A,B) would you require to carry out the transformation shown below:
Cyclohexene --- A----> DiBromocyclohexane -----B----> 1,3 Cyclohexadiene
a.Br2, HCl
b.HBr, KOH/Ethanol
c. Br2, KOH/Ethanol
d. NBS, KOH
e. None are correct
d. NBS, KOH
The correct answer is:
c. Br2, KOH/Ethanol
To carry out the transformation from cyclohexene to diBromocyclohexane, the reagent required is Br2 (Bromine) in the presence of KOH (Potassium Hydroxide) and Ethanol.
Then, to further convert diBromocyclohexane to 1,3 Cyclohexadiene, the reagent required is Br2 (Bromine) in the presence of KOH (Potassium Hydroxide) and Ethanol.
Therefore, the correct reagents for the given transformation are Br2, KOH/Ethanol.
