Na²O² is less stable than [Na₂ ] 0². This lesser stability is due to
(A)the very small size of the Na²+ ion
(B)the large size of the O²- ion relative to Na²+
(C) the instability of oxide ions in the presence of 2+ ions W
(D)more energy is required to ionize sodium than would be realized
in the attraction between Na²+ and 0²-
(Ethe statement is false, both materials are stable.

Chelation effect change two entropy
1. The entropy of the conformation of molecule.bidentate ligand is with more constraint than monodentate ligand.but it’s relatively small
2.the entropy of freely moving molecule.Bidentate ligand forms a more complete structure with less interaction with other entity.Therein,the increase number of free moving molecules.
The above result is the the increasing entropy of chelator than monodentate ligand. In the opinion of free energy,increasing entropy means the the product are more stable.
