    Is there a difference between the following?

    2-bromo-4-methylhexane & 4-methyl-2-bromohexane

    In representing 1-propanol, is there a difference between: CH2(OH)CH2CH3 & CH3CH2CH2OH

    Thanks.

    Yea, one of them is named wrong. If it's a haloalkane you use the halogen's prefix e.g fluoro-/chloro-/bromo-/iodo-.

    Both are the same compound. Just reflect it (right-left) and you'll see they are not isomers. If you are asking which was the correct way of writing it, both are correct. Although it is usual to put the functional group on the right

    So, is representing an organic compund by either 2-bromo-4-methylhexane or 4-methyl-2-bromohexane considered the same? And, doesn't matter if bromo or methyl come first?

    The order does matter, yes.

    According to the IUPAC rules, the substituents are named in alphabetic order. So that one would be 2-bromo-4-methylhexane.

    Of course, it would still be understood if you put them the other way round, it's just not good chemical manners.
