Vedclass · Answer

(B) The reaction described is the carbylamine test,which is characteristic of primary amines.The reaction is: $C_6H_5NH_2 + 3 KOH + CHCl_3 	o C_6H_5NC + 3 KCl + 3 H_2O$.Here,$(Y)$ is $CHCl_3$ (chloroform).Chloroform $(Y)$ is prepared by the haloform reaction using ethanol $(Z)$ and chlorine in the presence of slaked lime $(Ca(OH)_2)$:$C_2H_5OH + Cl_2$ $\xrightarrow{Ca(OH)_2} CH_3CHO$ $\xrightarrow{Cl_2} CCl_3CHO$ $\xrightarrow{Ca(OH)_2} CHCl_3$.Thus,the compound $(Z)$ is $C_2H_5OH$ (ethanol).

An aromatic amine $(A)$ was treated with alcoholic potash and another compound $(Y)$ to form a foul-smelling gas with the formula $C_6H_5NC$. Compound $(Y)$ was formed by reacting a compound $(Z)$ with $Cl_2$ in the presence of slaked lime. The compound $(Z)$ is:
