But-$2$-ene

Vedclass · Answer

(C) The Markovnikov rule states that when an unsymmetrical reagent adds to an unsymmetrical alkene,the negative part of the reagent attaches to the carbon atom with fewer hydrogen atoms.But-$2$-ene $(CH_3-CH=CH-CH_3)$ is a symmetrical alkene.Because it is symmetrical,the addition of $HBr$ results in the same product regardless of which carbon the bromine atom attaches to.Therefore,the concept of the Markovnikov rule is not applicable to symmetrical alkenes like but-$2$-ene.

Which of the following compounds does not follow the Markovnikov rule when reacting with $HBr$?

$HCl$ does not show the peroxide effect because the reaction mechanism involves the following steps:
$CH_3-CH=CH_2 + \dot{X} \to CH_3-\dot{C}H-CH_2X$ $(I)$
$CH_3-\dot{C}H-CH_2X + HX \to CH_3-CH_2-CH_2X + \dot{X}$ $(II)$
Why does $HCl$ fail to undergo this reaction?
