STEP 1. ELECTROPHILIC ADDITION OF H:
The more substituted double bonds attacks the hydrogen of HI. The result is the formation of an allylic carbocation and the iodide ion:
STEP 2. RESONANCE OF THE ALLYLIC CARBOCATION:
Allylic carbocation are very stable sue to the resonance effect:
STEP 3. ATTACK OF IODIDE
The attack of iodide in the second resonence form, produces the substance we expected to form:
