Vedclass · Answer

(A) In the acid-catalyzed dimerization of isobutylene,the first step is the protonation of the alkene to form a stable tert-butyl carbocation,$(CH_3)_3C^+$. In the next step,this carbocation acts as an electrophile and is attacked by another molecule of isobutylene. The $\pi$-electrons of the alkene attack the positively charged carbon of the carbocation,as shown in the correct mechanism.

Which of the following best describes the flow of electrons in the acid-catalyzed dimerization of $(CH_3)_2C = CH_2$?
