The question seems to be asking for a match between the compounds in Column-I and their features in Column-II. Here's a possible answer:

(a) CoCl3·5NH3 matches with (q) Secondary valencies are more than four. This is because the coordination number of Co in this complex is 6 (5 from NH3 and 1 from Cl), which is more than four.

(b) CoCl3·3NH3 matches with (p) Aqueous solution conducts electricity due to dissociation of solute molecules. This is because the complex can dissociate into ions in solution, allowing it to conduct electricity.

(c) PtCl2·2NH3 matches with (r) Will show isomerism. This is because the complex has a coordination number of 4, which allows it to exhibit geometrical isomerism.

(d) PtCl4·2HCl matches with (s) Purple colour compound. This is because the complex is known to be a purple compound.
