Write the chemical equation for the following.
Question
$\text{C}_2\text{H}_5\text{NH}_2 + \text{CHCl}_3 + \text{KOH(alc.)} \xrightarrow{warm}$
Answer
Answer
Official answer keyEquation: $\mathrm{C_{2}H_{5}NH_{2}} + \mathrm{CHCl_{3}} + 3\mathrm{KOH} \xrightarrow{\text{alc.}\text{ }\text{KOH}\text{,}\text{ }\text{warm}} \mathrm{C_{2}H_{5}NC} + 3\mathrm{KCl} + 3\mathrm{H_{2}O}$
Reaction: Carbylamine reaction
Product: ethyl isocyanide
Carbylamine reaction: a primary amine with chloroform and alcoholic KOH on warming gives ethyl isocyanide.
