Find the correct statement for Ethylenediamine (en) 

Formula- ${\mathrm{C}}_2{\mathrm{H}}_4{\left({\mathrm{NH}}_2\right)}_2$

${\mathrm{H}}_2\mathrm{N} - {\mathrm{CH}}_2 - {\mathrm{CH}}_2 - {\mathrm{NH}}_2$

Because lone pairs of electrons are present, it acts as a Bidendate ligand that can occupy two positions.

There are many different types of ligations, such as metal-metal bonding interactions with coordination bonds, $\mathrm{\pi }$-interactions with transition metal complexes, and chelation involving compounds such as EDTA (ethylenediamine-tetraacetic acid).
