8) этан (алкан), этанол (спирт), пропановая кислота (карбоновые кислоты), гептанол (спирт)

10) при добавлении в каждую из пробирок раствора йода, раствор крахмала приобретёт синий цвет. При добавлении в каждую пробирку Cu(OH)2 раствор глицерина приобретёт ярко-синий цвет. Методом исключения находим пробирку с кислотой. Так же можно добавить в растворы индикатор - лакмус, в пробирке с кислотой он обретёт красный цвет

C2H5OH=H2SO4,t>140°=>C2H4+H20

C2H4+H2=Ni,t=>C2H6

C2H6+Br2=>C2H5Br+HBr
