Addition of `X_(2)` on alkene is electrophilic additon reaction.Reaction proceed through the formation of 3- membered cyclic halonium ion. Nucleophile `X^(-)` attacks from backside of cyclic halonium ion hence total reaction is anti addition reaction.If this reaction proceed polar solvent then solvent itself acts as nucleophile. Which of the following statements is incorrect?A. Symmetrical trans alkene gives 2 products on reaction with `Br_(2)//CCI_(4)`B. Symmetrical cis alkene gives 2 products on reaction with `Br_(2)//C Cl_(4)`C. Trans alkenes give erythro productD. Cis alkenes give threo product

1.	Addition of `X_(2)` on alkene is electrophilic additon reaction.Reaction proceed through the formation of 3- membered cyclic halonium ion. Nucleophile `X^(-)` attacks from backside of cyclic halonium ion hence total reaction is anti addition reaction.If this reaction proceed polar solvent then solvent itself acts as nucleophile. Which of the following statements is incorrect?A. Symmetrical trans alkene gives 2 products on reaction with `Br_(2)//CCI_(4)`B. Symmetrical cis alkene gives 2 products on reaction with `Br_(2)//C Cl_(4)`C. Trans alkenes give erythro productD. Cis alkenes give threo product
Answer» Correct Answer - A Trans-alkane give meso product which is optically inactive
