30th Jan @ 5:00PM for Grade 1 to 10
Which of the following pairs is most likely to form the desired compounds? Describe the periodic trends and physical basis for your answer in each case. (a) EDTA ion with Cs+ (b) K+ ion to form complex with [222] cryptand. Which of the following pairs is most likely to form the desired compounds?

The smaller 2.2.1 crypt-ligandforms more stable compounds with Li+and Na+, whereas the larger 2.2.2 crypt-ligand forms more stable compounds with K+and Rb+. 18-crown-6 is strongly size selective for K+.The increased stability of thesepolydentate ligandcomplexes is due to thechelate effect: That is that complexes containing chelate (polydentate) rings are more stable than thesystemwhich is as similar as possible but contains fewer or no rings. The extra stability is the chelate effect.
