Iodine monochloride (IClI\text{Cl}ICl) reacts with propene (CH3CH=CH2CH_3CH=CH_2CH3CH=CH2) via an electrophilic addition mechanism. Chlorine is more electronegative than iodine.
Which of the following is the major organic product and the correct explanation for its formation?
1-chloro-2-iodopropane, because the reaction proceeds via the more stable secondary carbocation intermediate.
2-chloro-1-iodopropane, because the reaction proceeds via the more stable primary carbocation intermediate.
2-chloro-1-iodopropane, because the reaction proceeds via the more stable secondary carbocation intermediate.
1-chloro-2-iodopropane, because the reaction proceeds via the more stable primary carbocation intermediate.
