.An organic compound G has the following composition by mass: C = 64.88 %; H = 13.49 %; O= 21.63 % Oxidation of G using acidified potassium manganate(VII) gives H which is positive to both the 2,4-dinitrophenylhydrazine and Tollen's reagent test. Treatment of G with a concentrated acid forms J which decolourises bromine. J reacts with hydrogen chloride to give K. K undergoes alkaline hydrolysis to form L which is a structural isomer of G. L resists oxidation by acidified potassium manganate(VII) solution. (a) Give the name and structural formula for G, H, J, K and L.​
