11doubts u may hv :
i) by the delocalisation at the right , at the middle ,secondary carbocation is formed as a result of delocalisation . if it would hv been other way then , primary carbocation would hv been formed. ( cn also judge on the basis of stability of carbanion. )
ii) Addition of I in the form of I+ but elimination in the form of I- as it is a good leaving group.
iii) O-Li group or O-Et groups can't hv been directly substituted or eliminated.[9]
