Answer:
CoCl³
Explanation:
it is bcoz the charge on Co is +3. So its polarization power is high as compared to the other cations given. and according to fajaan's rule the polarization power of the cation is directly proportional to the covalent character. (inversely proportional to ionic character.)
so CoCl³ is the least ionic.
