Vedclass · Answer

(D) $1$. Acidic hydrolysis: $CH_3CN + 2H_2O + H^+ \rightarrow CH_3COOH + NH_4^+$. This is a correct property.$2$. Alkaline hydrolysis: $CH_3CN + OH^- + H_2O \rightarrow CH_3COO^- + NH_3$. This is a correct property.$3$. Tautomerization: $CH_3-C \equiv N \rightleftharpoons CH_2=C=NH$. It does not form methyl isocyanide $(CH_3NC)$ via tautomerization.$4$. Carbylamine reaction: The carbylamine reaction is characteristic of primary amines $(R-NH_2)$,not nitriles $(R-CN)$. Therefore,$CH_3CN + CHCl_3 + KOH$ does not produce carbylamine. Both options $C$ and $D$ are incorrect properties for ethanenitrile,but in the context of standard chemistry questions,the carbylamine reaction is specifically a test for primary amines,making $D$ the most distinct incorrect property.

List-$I$ (Reagents used)	List-$II$ (Compound with functional group detected)
$A.$ Alkaline solution of copper sulphate and sodium citrate	$I.$ $C_6H_5CH(OH)CH_3$
$B.$ Neutral $FeCl_3$ solution	$II.$ $CH_3CH(NH_2)CH_3$
$C.$ Alkaline chloroform solution	$III.$ $C_6H_5CH_2CHO$
$D.$ Potassium iodide and sodium hypochlorite	$IV.$ $m-C_2H_5C_6H_4OH$

Which of the following properties is $NOT$ applicable to $CH_3CN$ (Ethanenitrile)?
