What is the electrophile in the electrophilic substitution reaction of benzene using oleum and conc. H2SO4
Correct answer: A. SO3
- A. SO3
- B. NO2+
- C. NO3
- D. NO+
Explanation
In the electrophilic substitution reaction of benzene using oleum and concentrated sulfuric acid, the electrophile is the sulfur trioxide (SO3) species. This electrophile is formed from the reaction of sulfur trioxide with sulfuric acid in oleum. The other options provided such as NO2+, NO3-, and NO+ are not electrophiles due to their positive or negative charges and instability, making them unsuitable for electrophilic reactions with benzene.
