When trans-2-butene is reacted with B{{r}_{2}} then product is formed:A. Racemic-2,3-dibromobutaneB. Meso-2,3-dibromobutaneC. d-2,3-dibromobutaneD. l-2,3-dibromobutane
When trans-2-butene reacts with Br2 the product formed is meso-2,3-dibromobutane.
Here’s why:
The reaction of alkenes with bromine (Br2) typically leads to the formation of a dibromide through a bromonium ion intermediate.
For trans-2-butene, which has the bromine atoms added to opposite sides of the double bond, the resulting dibromide will have a meso form.
The meso compound has internal symmetry and is achiral despite having stereocenters.
So the correct answer is B. Meso-2,3-dibromobutane.
