The question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses:
Assertion: Co-ordination number of cobalt in the complex `[Co(en)_3]^(3+)` is six.
Reason: Ethylenediamine acts as a bidentate ligand.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a 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.

Answer

A

Explanation

In`H_2oversetuarrddotN-H_2C-CH_2-oversetuarrddotNH_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, there by given coordination number six.
