A hydrocarbon gas decolourises alkaline potassium permanganate and gives precipitate with ammonical silver nitrate. The gas is :
${C H}_{4}$
$C_{2} H_{2}$
$C_{2} H_{4}$
$C_{2} H_{6}$

Question

A hydrocarbon gas decolourises alkaline potassium permanganate and gives precipitate with ammonical silver nitrate- The gas is -CH-4-C-2-H-2-C-2-H-4-C-2-H-6-

C2H2- acetylene is an alkyne and thus forms precipitate with ammonical silver nitrate solution- tollen-apos-s reagent- Also alkynes decolourises alkaline-xA0-potassium permanganate solution-

A hydrocarbon gas decolourises alkaline potassium permanganate and gives precipitate with ammonical silver nitrate. The gas is :CH4C2H2C2H4C2H6

C2H2; acetylene is an alkyne and thus forms precipitate with ammonical silver nitrate solution( tollen's reagent). Also alkynes decolourises alkaline potassium permanganate solution.
