It is closely related to simple halogenation and halohydration using hypohalous acids. In both cases, an electrophilic halogen adds to the C=C to form a cyclic halonium ion that is then opened when a Nu attacks. In this case, the first part is to recognise that because Cl is more electronegative than I and therefore, the ... marina mall cinema schedule
