Vedclass · Answer

(C) The reaction of $HBr$ with $2-$methyl$-1,3-$butadiene (isoprene) involves electrophilic addition to the conjugated diene system.$H^{+}$ adds to the terminal carbon to form the most stable carbocation, which is a resonance-stabilized allylic carbocation.At room temperature, the thermodynamic product, which is the more substituted alkene, is the major product.This corresponds to the $1,4-$addition product, which is $1-$bromo$-3-$methyl$-2-$butene.
