The species responsible for the superacidity of $\mathrm{SbF}_{5}-\mathrm{HSO}_{3} \mathrm{F}$ system is
(a)$\mathrm{HSO}_{3} \mathrm{F}$
(b)$\mathrm{SbF}_{5}$
(c)HF
(d)$\mathrm{H}_{2} \mathrm{SO}_{3} \mathrm{F}^{+}$
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
SbF₅ removes F⁻/stabilises the anion, so the protonated solvent H₂SO₃F⁺ is the superacidic species (d).
