chemistry p61 (liquid M)

[mido4help]

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

Mclovin you r right it is an alkene

guys isnt paper 6 core so y did they give us questions related to organic chemistry thats unfair!

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

I wrote it was an organic substance which doesnt contain starch as its colour was brown and their was 2 marks btw
and the colour of the iodide what did u guys write and what happen s when getting a splint near it?

 

[Parfals]

Does any one remember the initial difference??????????????????????????

 

[She7taman]

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.

@She7taman
Was there even a potassium bromide?
