Question 23 :
An organic compound was used&#160;with sodium metal and extracted with distilled&#160;water. On adding freshly prepared $FeSO_{4}$&#160;solution followed by the addition of $FeCl_{3}$ and&#160;dil. $HCl$ produced a greenish blue solution. 0.30g&#160;of the organic compound after Kjeldahlisation&#160;evolved a gas $(X)$ which was passed on 100 ml&#160;of 0.1 M $H_{2}SO_{4}$.
