    In writing the condensed formula of hexanal, are those two ways of writing the formula correct?

    CH3CH2CH2CH2CH2CHO

    CHOCH2CH2CH2CH2CH3

    Thanks.

    the first one is correct.

    the second one isn't. It makes it look like some kind of "mis-spelled" ether. (Because it looks like the first two carbons are attached via an oxygen atom)

    So, does this make the second formula correct? Or, it becomes alcohol in this case?

    COHCH2CH2CH2CH2CH2CH3

    If you want to put the aldehyde on the LHS you could write OHC-

    as in

    OHCCH2CH2CH2CH2CH2CH3

    SWE you are spending a huge amount of time on nomenclature and writing formula. Why not invest some of this time in studying the acdl website official IUPAC systems.
