The equivalents of ethylene diamine required to replace the neutral ligands from the coordination sphere of the trans-complex of CoCl3 . 4NH3 is _________. (Round off to the Nearest Integer).
Answer (integer)
2
Solution
<p>$[Co{(N{H_3}]_4}C{l_2}]Cl + 2en \to [Co{(en)_2}C{l_2}] + 4N{H_3}$</p>
<p>NH<sub>3</sub> is the neutral monodentate ligand. Ethylene diamine is a neutral didentate ligand.</p>
<p>$${H_2}\mathop N\limits^{ \bullet \,\, \bullet } - C{H_2} - C{H_2} - \mathop N\limits^{ \bullet \,\, \bullet } {H_2}(en)$$</p>
<p>So, two ethylene diamine are equivalent to four 'NH<sub>3</sub>' ligand.</p>
