Question

What product is formed when $$\mathrm{R}-\mathrm{C}\equiv \mathrm{N}$$ is hydrolysed?

विकल्प

• $$\begin{array}{c}\mathrm{R}-\mathrm{C}-\mathrm{OH}\\ ||\phantom{..}\\ \mathrm{O}\phantom{..}\end{array}$$

• $$\begin{array}{c}\mathrm{R}-\mathrm{C}-\mathrm{H}\\ ||\\ \mathrm{O}\end{array}$$

• $$\begin{array}{c}\mathrm{R}-\mathrm{C}-\mathrm{R}\\ ||\\ \mathrm{O}\end{array}$$

• $$\begin{array}{c}\mathrm{R}-\mathrm{C}-\mathrm{O}-\mathrm{R}\\ ||\phantom{.....}\\ \mathrm{O}\phantom{.....}\end{array}$$

Answer 1

$$\begin{array}{c}\mathrm{R}-\mathrm{C}-\mathrm{OH}\\ ||\phantom{..}\\ \mathrm{O}\phantom{..}\end{array}$$

Explanation:

$$\begin{array}{c}\phantom{..................}\mathrm{OH}\phantom{...............}\mathrm{O}\phantom{................}\mathrm{O}\phantom{.}\\ \phantom{.............................}|\phantom{.................}||\phantom{.................}||\phantom{...........}\\ \underset{\mathrm{Alkyl}\mathrm{cyanide}}{\mathrm{R}-\mathrm{C}\equiv \mathrm{N}}+\mathrm{H}-\mathrm{OH}⟶\mathrm{R}-\mathrm{C}=\mathrm{NH}⟶\mathrm{R}-\mathrm{C}-\mathrm{NH}{\phantom{A}}_2\stackrel{\mathrm{H}{\phantom{A}}^{+}}{\to }\underset{\mathrm{Carboxylic}\mathrm{acid}}{\mathrm{R}-\mathrm{C}-\mathrm{OH}}+\mathrm{NH}{\phantom{A}}_3\end{array}$$
