what amine is forms an N-nitrosoamine on treatment with NaNO2 in dilute aqueous acid at 0' C?

To identify the anime that forms an N-nitrosoamine on treatment with NaNO2 in dilute aqueous acid at 0°C, we need to understand the reaction conditions.

The reaction you mentioned involves the use of sodium nitrite (NaNO2) in dilute aqueous acid at low temperature (0°C). This reaction is known as the nitrosation reaction and is commonly used to convert primary amines into N-nitrosoamines.

In this reaction, the NaNO2 and the amine react in the presence of acid to form an N-nitrosoamine. The exact amine that forms an N-nitrosoamine in this reaction depends on the specific amine being used.

Given that you haven't provided the specific amine, we cannot determine the exact anime that forms an N-nitrosoamine in this specific reaction. If you can provide more details or context regarding the amine you are referring to, we can help you further.
