The cations formed upon dissolving $\mathrm{SnF}_{4}$ and $\mathrm{AuF}_{3}$ in liquid $\mathrm{BrF}_{3}$ separately, respectively are

(a)$\mathrm{SnF}_{3}^{+}$and $\mathrm{BrF}_{2}^{+}$

(b)$\mathrm{BrF}_{2}^{+}$and $\mathrm{AuF}_{2}^{+}$

(c)$\mathrm{BrF}_{2}^{+}$only

(d)$\mathrm{SnF}_{3}^{+}$and $\mathrm{AuF}_{2}^{+}$

Answer

Answer: C ✓ checked by 4AB · confidence high

Explanation

SnF₄ and AuF₃ are fluoride acceptors, so only BrF₂⁺ cations form (c).
