Reason: Ethylenediamine acts as a bidentate ligand.A. (a) If both assertion and reason are true and the reason is the correct explanation of the assertion.B. (b) If both assertion and reason are true but reason is not the correct explanation of the assertion.C. (c) If assertion is true but reason is false.D. (d) If assertion is false but reason is true.
Answer» Correct Answer - A In `H_2overset(uarr)overset(..)N-H_2C-CH_2-overset(uarr)overset(..)NH_2` two ammine nitrogen atoms act as donor atoms. So, it acts as a bidentate ligand. Hence, there are six `sigma`-bonds between metal and ligands, thereby given coordination number six.
