There is two answers for this question as my chemistry teacher said
1- It is hydrocarbon and it's alkane
2- Or simply organic compound and ethanol

Because most of organic chemistry is core...read the syllabus and don't just write stupid, unqualified assertions.

what did u guys right about the flame produced by liquid N and wat was the colour of iquid N

I believe there was no flame on N , and I didn't notice "Liquid N" so I wrote purple solid XDDD

Speaking of which, there's another controversial question:

The potassium bromide solution that was in the question. He approached a lighted splint, what would be the result?

I believe it would not burn, and that the splint would be extinguished. This is because only organic solvents burn, so despite the presence of potassium, there would be no lilac flame, because it's in a solution.

If you're in doubt, you can think of it this way. If you have a solution of sodium chloride (same principle, metal halide in a solution) and approach a match, would it burn? Go get some salt and water if you're still stubborn.

My 2 cents.
