4 Answers – What are the uses of ‘NaNO2/HCl’ in organic chemistry …

The reagent NaNO2/HCl is used in preparation of Nitrous Acid in the laboratory. The nitrous acid (HNO2) is a very unstable acid, therefore cannot be preserved, and thus it has to be prepared at the time of the reaction. Using Nitrous Acid, we can perform a diazotization reaction with primary amines. Primary aromatic amines …

Products of NaNO2 and HCl? | Yahoo Answers

Despite the fact that there are four other answers so far, let me set this straight. On the one hand we have the group that says the products are NaCl and HNO2 as if there are actually molecules of NaCl formed, which, of course, there aren’t. And then we have the lone hold out, Daniel, who says there won’t …

Diazotisation – Organic Chemistry Portal

A convenient and general onestep preparation of aromatic and some heterocyclic iodides in good yields includes a sequential diazotizationiodination of aromatic amines with KI, NaNO2, and pTsOH in acetonitrile at room temperature.
