Do you know that question where it came you methylcyclohexene, it asked for the strutures when you you react it with H2 and HBR - with the H2 the double bond goes - with the HBR there are two possible structure, one where you put the H with carbon 1 with the methyl or you put it with the other C that was part of the double bond, ie. carbon 2 - and vice versa for the second structure. I did one of the structures right and got the last one wrong because I think, well I am sure, that I put the BR on carbon 3 which really didn't have much to do with the double band and was already linked to 2 hydrogen atoms and 2 carbon atoms - so 2/3 there.


Oh I think I did exactly the same as you. As long as we get a mark for the right one, it should be alright :smile:
