Vedclass · Answer

(C) The reaction of $1,3$-butadiene with bromine $(Br_2)$ is an electrophilic addition reaction. Due to the resonance stabilization of the allylic carbocation intermediate,the addition can occur at the $1,2$-position (kinetic product) or the $1,4$-position (thermodynamic product). Therefore,a mixture of $3,4$-dibromobut-$1$-ene ($1,2$-addition product) and $1,4$-dibromobut-$2$-ene ($1,4$-addition product) is formed.

The addition reaction of $1,3$-butadiene with bromine yields ........
