when compound is treated with
when compound \( \mathbf{C} \) is treated with \( \boldsymbol{B} \boldsymbol{r}_{2} / \boldsymbol{C} \boldsymbol{C l}_{4} \)
- A. a meso dibromide is formed.
- B. four stereo-isomers of dibromides are fromed.
- C. racemic mixture of dibromides are formed.
- D. a pair of enantiomers of dibromides in unequal amount is formed.
Step-by-step solution
Compound C is typically a symmetrical cis-alkene (like cis-2-butene). Addition of Br2 in CCl4 proceeds via anti addition, and for a cis-alkene, this yields a vicinal dibromide with two chiral centers that has an internal plane of symmetry, resulting in a meso compound.
