<img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-7p04g3ehfo6jmctj.jpg" /> Isobutyl carbocation [ (CH)3 (CH)2-CH-(CH)2 ] will get rearranged to a more stable cation I.e., t-butyl cation.

Q. What will be the stable or major product when benzene ( $C_{6} H_{6}$ ) reacts with isobutyl chloride $[C ((C H)_{3})_{3} Cl]$ in the presence of anhydrous $A lC l_{3}$ ?

$t -$ butylbenzene

Isobutylbenzene

$n -$ butylbenzene

$sec -$ butylbenzene

Isobutyl carbocation $[(C H)_{3} (C H)_{2} - C H - (C H)_{2}]$ will get rearranged to a more stable cation I.e., t-butyl cation.

Q. What will be the stable or major product when benzene ( C6​H6​ ) reacts with isobutyl chloride [C((CH)3​)3​Cl] in the presence of anhydrous AlCl3​ ?

t− butylbenzene

Isobutylbenzene

n− butylbenzene

sec− butylbenzene

Isobutyl carbocation [(CH)3​(CH)2​−CH−(CH)2​​] will get rearranged to a more stable cation I.e., t-butyl cation.
