Identify the amine that does not form alcohol by the action of \(\mathrm{NaNO}_2\) and \(\mathrm{HCl}\).
- A \(\left(\mathrm{CH}_3\right)_3-\mathrm{C}-\mathrm{NH}_2\)
- B \(\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{NH}_2\)
- D \(\left(\mathrm{CH}_3\right)_2-\mathrm{NH}\)
Answer & Solution
Correct Answer
(D) \(\left(\mathrm{CH}_3\right)_2-\mathrm{NH}\)
Step-by-step Solution
Detailed explanation
\(\mathrm{R}-\mathrm{NH}_2 \stackrel{\mathrm{NaNO}_2+\mathrm{HCl}}{\longrightarrow} \mathrm{R}-\mathrm{OH}+\mathrm{N}_2+\mathrm{H}_2 \mathrm{O}\)
Thus, \(\left(\mathrm{CH}_2\right)-\mathrm{NH} \rightarrow 2^{\circ}\) amine, do not give alcohol with \(\mathrm{NaNO}_2\) \& \(\mathrm{HCl}\).
Thus, \(\left(\mathrm{CH}_2\right)-\mathrm{NH} \rightarrow 2^{\circ}\) amine, do not give alcohol with \(\mathrm{NaNO}_2\) \& \(\mathrm{HCl}\).
