Answer 2

Answer:

Primary amines can be converted into alkanols by reaction with 3. NaNO₂ and dil. HCl

Explanation:

• Amines when reacted with NaNO₂ and dil. HCl forms an intermediate diazonium salt.
• Now this diazonium salt gets removed and a carbocation is formed.
• The carbocation gets shifted and a secondary carbocation is formed as secondary carbocation is more stable than primary carbocation.
• Now, the OH⁻ ion of a water molecule attacks this secondary carbocation and an alkanol is formed.

The general reaction is written as follows:

Primary amine + NaNO₂ (dil. HCl) → [Diazonium salt] → Carbocation + OH⁻ → Alkanol

Therefore, primary amines on reaction with NaNO₂ and dil. HCl gives alkanols.
