Vedclass · Answer

(A) The addition of $HBr$ to unsymmetrical alkenes follows anti-Markovnikov's rule in the presence of peroxide (peroxide effect or Kharasch effect).However,for symmetrical alkenes,the product formed remains the same regardless of the presence or absence of peroxide because the molecule is symmetric.$2-$butene $(CH_3-CH=CH-CH_3)$ is a symmetrical alkene.Therefore,the addition of $HBr$ to $2-$butene yields $2-$bromobutane in both cases.

The alkene that will give the same product with $HBr$ in the absence as well as in the presence of peroxide is
