Question

A yellow metallic powder when burnt in a stream of fluorine produced a colourless, thermally stable and chemically inert gas ' X '. A gas ' Y ', which is colourless and consists of the same elements as are present in gas ' X ', is obtained by heating together sulphur dichloride and sodium fluoride. Gases ' X ' and ' Y ' respectively are (A) SF 4 and SF 6 (B) SF 4 and S 2 F 2 (C) SF 6 and SF 4. (D) None of these
