Vedclass · Answer

(B) The reaction involves the electrophilic addition of $HCl$ to $2$-methylbut-$1,3$-diene (isoprene). $1$. Protonation of the conjugated diene occurs at the terminal carbon to form the most stable carbocation,which is a resonance-stabilized allylic carbocation. $2$. The resonance hybrid allows for the attack of the chloride ion $(Cl^-)$ at different positions. $3$. The thermodynamic product $(TCP)$ is formed by the addition of $Cl^-$ to the more substituted end of the allylic system,resulting in $1$-chloro-$3$-methylbut-$2$-ene.
