Maximum polarization is caused by the cation of small size and large charge. and Maximum polarization of that anion takes place which is large and has high negative charge. Therefore, we can say that amount of polarisation is directly proportional to the charge on anion and cations and it is inversely proportional to the size of cation and directly proportional to the size of anion! So, 16 - (C) For next question, isoelectronic means same number of electrons. Count the number of electrons of all the species given in option...CO2 has 22 electrons. 6 is coming from C and 8 from O.

For 17, A, B and C are correct. Count the numbers of electrons first.

minimum polarisation will be brought upon by the cation of large radius.

Small radius means small size of the cation, Shib! and small sized cation causes high polarization i.e distortion of anion's electron cloud.

Then you easily explain this...that smaller cations and higher charge cations distorts the electron cloud of negatively charged ion...due to this...covalent character comes in ionic compound
