MCQ
Find out the incorrect statement.
  • A
    It gives total $9$ allylic brominated products.
  • All allylic brominated products are optically active.
  • C
    Substrate has $7$ allylic hydrogens.
  • D
    $\text{NBS}$ gives $Br$ constantly to reaction mixture.

Answer

Correct option: B.
All allylic brominated products are optically active.
In this reaction $\text{NBS}$ gives $Br$ constantly to reaction mixture which attacks at allylic position and forms bromo products.
Here, substrate has $7$ allylic hydrogens and forms $9$ allylic brominated products out of which this product is optically inactive.
