Ethoxy ethane when treated with conc: H2SO4 it produces:

Correct answer: B. Oxonium ion

  • A. Carbocation
  • B. Oxonium ion
  • C. Carbanion
  • D. Oxalate ion

Explanation

When ethoxy ethane is treated with concentrated H2SO4, the oxygen atom in ethoxy ethane donates a lone pair to the hydrogen ion from the acid, forming an oxonium ion. This ion is characterized by the oxygen atom having three bonds and a positive charge.Other options, such as carbocation and carbanion, involve charged carbon species, which are not relevant to this reaction. The oxalate ion is an entirely different anion not involved in the formation of an oxonium ion.
