When I added conc. H2SO4 to cyclohexene it turned black.
It seemed that some black solid was formed.
Is it that H2SO4 oxidises the cyclohexene to carbon?

Thanks!

I dont think so. If there's enough H2O in the medium it may form  CycloHexanol. Or a stronger possiblity is the purity of your chemicals. If you use impure chemicals side reactions may occur. Changing the reaction mixture's color. Boil the solution with activated carbon filter with gravity filteration to see the real color.
