Question

Which will form a racemic mixture when treated with br2 in presence of ccl4?

Answer 1

Alkenes react with either bromine or chlorine to form the corresponding dihalides ... Therefore, the bromination of cis- 2-butene yields a racemate of (2R,3R)- and

Answer 2

Alkenes will form a racemic mixture when bromine is treated with Br₂ in the presence of CCl₄

• Alkenes react with Br₂ in the presence of CCl₄ to give alkyl bromides.
• Mostly they
• forms a racemic mixture.
• For example, Cisbutene reacts with Br₂ in the presence of CCl₄ to give ±2,3 dibromo butane, which is a racemic mixture.
• Similarly, Many other alkenes give a racemization reaction when treated with Br₂ in the presence of CCl₄.
• During racemization, an optically active compound is converted into a 50:50 mixture of enantiomers with zero optical activity.
