How can this reaction is made to proceed in forward direction?
Reason : Addition of non-volatile solute into solvent results into depression of freezing point of the solvent.
$NH_2-CH_2-CH_2-NH_2 +$ $\begin{array}{*{20}{c}}

{|\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,} \\
{COO{C_2}{H_5}}
\end{array}$ $\xrightarrow{{Pyridne}}$ $[X]$
$[X]$ will be :
$(a)$ Heated : it is charred
$(b)$ $I_2$ solution : no violet colour
$(c)$ Fehling solution : reddish brown ppt. is observed
$(d)$ It does not reduce copper$(II)$ acetate to $Cu_2O$ . No red precipiated is observed in $5/ min$
The carboxylate which satisfy all the above observation
