The hydrolysis of benzenetrizonide yields three moles of which compound?

Benzenetrizonide is a triazene derivative containing three nitrogen atoms connected to a benzene ring. When it undergoes hydrolysis, water molecules attack the nitrogen–carbon bonds, breaking the triazene structure. This reaction releases small organic molecules depending on the arrangement of the nitrogen atoms and substituents.

The hydrolysis of benzenetrizonide is significant because it produces glyoxal (OCH–CHO). Glyoxal is the simplest dialdehyde, consisting of two aldehyde groups on adjacent carbon atoms. The reaction stoichiometry shows that one mole of benzenetrizonide produces three moles of glyoxal, due to the decomposition of the triazene moiety into small aldehyde units.

Glyoxal is a highly reactive compound used in resin formation, textile finishing, and organic synthesis. Its aldehyde groups make it useful in polymerization reactions and as a precursor for various chemical derivatives. The hydrolysis of benzenetrizonide demonstrates how nitrogen-containing aromatic derivatives can serve as precursors for smaller, functionalized aldehydes.

Other options listed are incorrect:

• 
  

  Glyoxime is not formed, as it contains oxime groups.

  
  


• 
  

  Benzaldehyde would be a product only if a single aldehyde were released per aromatic ring.

  
  


• 
  

  Glycol (ethylene glycol) is an alcohol, not an aldehyde, and is unrelated to this reaction.

  
  

This reaction highlights the conversion of nitrogen-rich aromatic derivatives into simple aldehydes, an important concept in organic synthesis and industrial chemistry
