A hydrocarbon, compound A (C₆H₁₀), burned with a yellow, almost nonsmoky flame. On catalytic hydrogenation over platinum catalyst, it absorbed 1 mol of hydrogen to form compound B. It also decolorized a Br₂–CH₂Cl₂ solution to yield a dibromo derivative, compound C. Ozonolysis of the hydrocarbon gave only one compound, D. Compound D gave a positive iodoform test when treated with iodine–sodium hydroxide solution. On treatment of compound D with an alcoholic solution of silver ammonium hydroxide, a silver mirror was formed within a few minutes. Identify the hydrocarbon A and compounds B–D.Identify the hydrocarbon A and compounds B–D.
