Statement-1 : `H_2N-NH_2` is a chelating ligand.
Statement-2 : A chelating ligand must possess two or more lone pairs at such a distance that it may form suitable strain free rings at the metal ion.

A

Statement 1 is True, Statement 2 is True, Statement 2 is Correct explanation for Statement 1.

B

Statement 1 is True, Statement 2 is True, Statement 2 is NOT a correct explanation for Statement 1.

C

Statement 1 is True, Statement 2 is False.

D

Statement 1 is False, Statement 2 is True.

Text Solution

Verified by Experts

The correct Answer is:
D
`H_2N NH_2` does not act as chelating ligand. The coordination by hydrazine leads to a three member highly unstable strained ring and thus it does not act as chelating agent.
