Question

F 2 formed by reacting K 2 MnF 6 with (A) SbF s  (B) MnF 3 (C) KSbF 6 (D) MnF 4

Tardigrade Admin · Accepted Answer

K 2 MnF 6 with SbF 5 forms F 2. In this reaction stronger I.ewis acid ShF 5 displaces the weaker one ( MnF 4) from its salt. MnF 4 is unstable and readily decompose to give MnF 3 and fluorine K 2 MnF 6+2 SbF 5 longrightarrow 2 KSbF 6+ underset text (unstable) MnF 4 MnF 4 longrightarrow M n F 3+(1/2) F 2
