Write the chemical equation for the following.
Question
$\text{CH}_3\text{CH}_2\text{Br} + \text{AgCN (alc.)} \rightarrow $
Answer
Answer
AIEquation: $\mathrm{CH_{3}CH_{2}Br} + \mathrm{AgCN} \xrightarrow{\text{alc.}} \mathrm{CH_{3}CH_{2}NC} + \mathrm{AgBr}$
Product: ethyl isocyanide
Ethyl bromide with alcoholic AgCN (largely covalent) gives ethyl isocyanide as the main product.
