Question

Correct option(s) is/are

• A. Reaction with $B{r}_2/CC{l}_4$, P will form a meso compound
• B. Reaction with $C{l}_2/H_{2}O$, P will form a diastereomer pair
• C. Reaction with $Os{O}_4/NaHS{O}_3$, P will form a racemic mixture
• D. Reaction with $HOI$, P will form a racemic mixture

Answer 1

Answer: (A), (C), (D)

The correct options are
A Reaction with $B{r}_2/CC{l}_4$, P will form a meso compound
C Reaction with $Os{O}_4/NaHS{O}_3$, P will form a racemic mixture
D Reaction with $HOI$, P will form a racemic mixture

The reactant given is vicinal dichloride which is present in meso form as we get it by drawing it in sawhorse projection.


The reactant undergoes elimination along with Finkelstein reaction to produces trans-butene (P).


As per option given :
(a) Reaction with $B{r}_2/CC{l}_4$, P will form a meso compound.


(b) Reaction with $C{l}_2/H_{2}O$, P will form a racemic mixture.



(c) Reaction with $Os{O}_4/NaHS{O}_3$, P will form a racemic mixture.


(d) Reaction with HOI, P will form a racemic mixture.
