Vedclass · Answer

(A) The reaction involves the electrophilic addition of $HBr$ to a conjugated diene,$2$-methylbuta-$1,3$-diene (isoprene). When $HBr$ is added to a conjugated diene,both $1,2$-addition and $1,4$-addition products can be formed. In the presence of excess $HBr$,the reaction proceeds further. However,the question asks for the major product of the initial addition step or the primary outcome of the reaction. The $1,4$-addition product is generally more stable due to the formation of a more substituted alkene. The reaction of $2$-methylbuta-$1,3$-diene with $HBr$ yields $1$-bromo-$3$-methylbut-$2$-ene as the major $1,4$-addition product.

The major product formed in the following reaction is:
