Vedclass · Answer

(C) In Lassaigne's test,an organic compound is fused with metallic sodium $(Na)$ to convert covalently bonded elements like nitrogen,sulfur,and halogens into water-soluble ionic salts. $1$. Nitrogen is converted to sodium cyanide $(NaCN)$. $2$. Sulfur is converted to sodium sulfide $(Na_2S)$. $3$. Halogens $(X)$ are converted to sodium halides $(NaX)$. $NaNC$ (sodium isocyanide) is not a product of this fusion reaction,as the cyanide ion formed is $CN^-$,not $NC^-$. Therefore,$NaNC$ is the correct answer.

List-$I$ (Reagent)	List-$II$ (Functional Group detected)
$A$. Sodium bicarbonate solution	$I$. Double bond/unsaturation
$B$. Neutral ferric chloride	$II$. Carboxylic acid
$C$. Ceric ammonium nitrate	$III$. Phenolic $-OH$
$D$. Alkaline $KMnO_4$	$IV$. Alcoholic $-OH$

In Lassaigne's test,the organic compound is fused with $Na$ followed by extraction with distilled water. Which of the following is not the product of this fusion reaction?
