Question

cis-2-Butene on treatment with bromine gives: (A) (+)-2,3 -dibromobutane (B) (-)-2,3 -dibromobutane (C) (±)-2,3 -dibromobutane (D) meso-2, 3-dibromobutane

Electophillic addition of halogen is an anti addition reaction so racemic mixture is obtained with cis-alkene.

Q. cis-2-Butene on treatment with bromine gives:

$(+) - 2, 3$ -dibromobutane

$(-) - 2, 3$ -dibromobutane

$(\pm) - 2, 3$ -dibromobutane

meso-2, 3-dibromobutane

Electophillic addition of halogen is an anti addition reaction so racemic mixture is obtained with cis-alkene.

Q. cis-2-Butene on treatment with bromine gives:
