Understanding Diazonium Salts
Diazonium salts are a class of organic compounds that contain a diazonium group, which is characterized by the presence of a nitrogen-nitrogen double bond (N2+). The general formula for diazonium salts can be expressed as follows:
  • RN2+X - where R represents an organic group (usually an alkyl or aryl group), and X is a counterion, often a halide like chloride (Cl), bromide (Br), or another anion.

Why Option A is Correct
The correct answer is option A (RN2+X) because:
  • Structure: The diazonium group (N2+) is positively charged, which is essential for its reactivity in various chemical reactions, such as electrophilic aromatic substitution.
  • Counterion: The presence of an anion (X) balances the charge, making the compound stable. Common counterions include halides or sulfate groups.
  • Reactivity: Diazonium salts are highly reactive and can be transformed into various functional groups, making them valuable intermediates in organic synthesis.

Other Options Explained
- RN: This does not represent a diazonium salt as it lacks the diazonium group.
- RX: This structure denotes an alkyl or aryl halide but does not involve the diazonium component.
- RN2+HSO4: While this might imply a diazonium sulfate, it is not the general formula for all diazonium salts.
Conclusion
In summary, diazonium salts are characterized by the structure RN2+X, which highlights their unique properties and reactivity, making them significant in organic chemistry.
