Assertion : EDTA forms complex with divalent metals of -series in the ratio of . Reason : EDTA has four groups.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
EDTA is a hexadentate ligand, forming stable 1:1 complexes with central metal ions through six donor atoms, two nitrogen, and four oxygen atoms. So the option (2) is correct.

The most stable complex among the following is
1
2
3
4
Explanation:
Stability of a complex depends upon the strength of ligand and charge of the central metal ion. Stability of complex strength of ligand charge of central metal ion. Among the given complexes, in the charge of central metal ion is highest, i.e. +1 while is the strongest field ligand. Hence, is the most stable complex among the given complexes.
