B

bidendate ligand and can occupy two positions in coordination polyhedron

C

polydendate ligand

D

tridendate ligand and occupy three positions in coordiantion polyhedron

Text Solution

Verified by Experts

The correct Answer is:
B
Ethylenediamine is on organic compound with formula `C_(2) H _(4) (NH_(2))_(2).`
`H _(2) overset(* *)N-CH_(2) -CH_(2) -overset(* *)NH_(2)`
It act as a bidentate ligand due to the presence of lone pair of electrons on nitrogen atoms and can occupy two positions.
