Question

Consider the complete, chemically balanced equation representing the formation of benzenediazonium chloride directly from aniline, sodium nitrite, and hydrochloric acid under ice-cold conditions. How many total moles of water ($H_2O$) are formally produced as a byproduct per single mole of aniline consumed?

Prashant Kotian · Accepted Answer

Correct answer: 2. The diazotization of a primary aromatic amine requires nitrous acid (), which is unstable and generated *in situ* from sodium nitrite and a strong mineral acid. The overall balanced chemical equation is: . Thus, exactly moles of water are produced for every mole of aniline reacted.
